  • Another program conflicts with Outlook.

Note

  • This issue may occur for one or more of the reasons in this section. To fix this issue, you may have to follow the troubleshooting steps in the Resolution section.
  • Many of these items can be automatically checked by the Microsoft Support and Recovery Assistant (SaRA). To start the automated checks, follow these steps:
    1. Install the Outlook Advanced Diagnostics tool.
    2. Select Run when you are prompted by your browser.
    3. In the report that's generated, review the items on the Issues found tab. For configuration details about Outlook, Windows, and your computer, review the settings on the Detailed View tab.

Resolution

To resolve this problem, make sure that your computer meets the Outlook 2016 system requirements, Outlook 2013 system requirements or Outlook 2010 system requirements.

Note

These steps are provided in a specific order based on commonality and complexity. Follow these steps in the given order.

Step 1 - Install the latest updates

The Office installation on your computer might not be up to date. This might be because Windows Update is not configured on your computer to automatically download and install recommended updates. By installing important, recommended, and optional updates, you can often correct problems by replacing out-of-date files and fixing vulnerabilities. To install the latest Office updates, click the link for your version of Windows, and then follow the steps in the article:

Make sure that the latest updates for Outlook are installed. For more information, see How to install the latest applicable updates for Microsoft Outlook (US English only).

Step 2 - Make sure that Outlook is not in use by another process

Performance may be decreased if you use the Outlook AutoArchive feature or sync to Outlook with a mobile device. This is because these processes can use a large number of resources.

If Outlook is in use by another process, this information is displayed in the status bar at the bottom of the screen. If you try to perform other actions while Outlook is in use, Outlook may not respond. Let the task in process finish its job before you try another action.

Step 3 - Check the problem caused by external content

To resolve this issue, use one of the following methods:

  • Prevent Outlook to download external contents. To do this, go to File > Options > Trust Center > Automatic Download, select the following two options:
    • Don't download pictures or other content automatically in HTML e-mail option.
    • Warn me before downloading content when editing, forwarding, or replying e-mail.
  • Avoid sending such an email with external source.

Step 4 - Investigate possible add-in issues

Although add-ins can enhance your user experience, they can occasionally interfere or conflict with Outlook. Try to start Outlook without any add-ins running.

How to start Outlook without add-ins

  1. Do the following, as appropriate for your operating system:
    • If you are running Windows 8, swipe in from the right edge of the screen, and then tap Search. (If you are using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then select Search.) Type Run in the search box, and then tap or select Run.
    • If you are running Windows 10, Windows 7 or Windows Vista, select Start.
    • If you are running Windows XP, select Start, and then select Run.
  2. Type Outlook.exe /safe, and then select OK.
  3. If the problem is resolved, select Options on the File menu, and then select Add-Ins.
  4. Select COM Add-ins, and then select Go.
  5. Clear all the check boxes in the list, and then select OK.
  6. Restart Outlook.

If the problem does not occur after you restart Outlook, one of the add-ins is likely the cause of the problem. Restore the add-ins one at a time until the problem does occur to determine which add-in is causing the problem.

Step 5 - Check whether your mailbox is too large

As your mailbox size increases, more resources are required to open each folder. If you have a large number of items in any single folder, you may experience performance issues during certain operations. For more information, see Outlook performance issues when there are too many items or folders in a cached mode .ost or .pst file.

We recommend that you move several items in your larger folders to separate folders, or that you archive those items by using the AutoArchive feature.

How to create a folder

  1. On the Folder tab, select New Folder in the New group.

  2. In the Name box, enter a name for the folder.

  3. In the Select where to place the folder list, select the location for the new folder.

    Note

    The new folder will become a subfolder of the folder you select.

  4. Select OK.

To manage your mailbox by reducing the size of the Outlook data file, see Reduce the size of Outlook Data Files (.pst and .ost).

To manage your mailbox by using the AutoArchive feature, see AutoArchive settings explained.

Step 6 - Check whether your AppData folder is being redirected to a network location

Outlook stores certain data, such as email signatures and the spelling checker dictionary, in the AppData folder. If the network is performing slowly, Outlook must wait for read and write operations to the AppData directory to finish.

How to disable redirection of the AppData directory

  1. Exit Outlook.

  2. Start Registry Editor. To do this, use one of the following procedures, as appropriate for your version of Windows:

    • Windows 10 or Windows 8: Press Windows Key+R to open a Run dialog box. Type regedit.exe and then press OK.
    • Windows 7: Select Start, type regedit.exe in the search box, and then press Enter.
  3. In Registry Editor, locate and then select the following subkey:

  4. Locate and then double-click the AppData value.

  5. In the Value data box, type the following path, and then select OK:
      %USERPROFILE%\AppData\Roaming

    Edit string image

  6. Exit Registry Editor.

Step 7 - Repair Office programs

You can automatically repair your Office program files to resolve such problems as Outlook freezing or not responding.

How to automatically repair Office

  1. Exit any Microsoft Office programs that are running.
  2. Open Control Panel, and then open the Add or Remove Programs item (if you are running Windows XP) or Programs and Features (if you are running Windows 10, Windows 8, Windows 7, or Windows Vista).
  3. In the list of installed programs, right-click Microsoft Office 2016, Microsoft Office 2013 or Microsoft Office 2010, and then select Repair.

Step 8 - Repair Outlook data files

When you install Outlook, an Inbox repair tool (scanpst.exe) is also installed on your PC. The Inbox repair tool can resolve problems by scanning your Outlook data files, and repairing errors. To use the Inbox repair tool, exit Outlook, and then follow the steps in Repair Outlook Data Files (.pst and .ost).

Step 9 - Check whether antivirus software is up-to-date or conflicts with Outlook

If your antivirus software is not up-to-date, Outlook may not function correctly.

How to check whether antivirus software is up to date

To keep up with new viruses as they are created, antivirus software vendors periodically provide updates that you can download from the Internet. Download the latest updates by visiting your antivirus software vendor's website.

For a list of antivirus software vendors, see Consumer antivirus software providers for Windows.

How to check whether antivirus software conflicts with Outlook

If your antivirus software includes integration with Outlook, you may experience performance issues. You can disable all Outlook integration within the antivirus software. Or, you can disable any antivirus software add-ins that are installed in Outlook.

Important

When you change your antivirus settings, this may make your PC vulnerable to viral, fraudulent, or malicious attacks. We do not recommend that you try to change your antivirus settings. Use this workaround at your own risk.

You may have to contact your antivirus software vendor to determine how to configure the software to exclude any integration with Outlook or to exclude scanning in Outlook.

Step 10 - Create a user profile in Outlook

To create a user profile, follow these steps:

  1. In Control Panel, select Programs, select User Accounts, and then select Mail to open Mail items.

  2. Select Show Profiles.

  3. Select the profile that you want to remove, and then select Remove.

  4. Select Add.

  5. In the Profile Name dialog box, type a name for the profile.

  6. Specify the user name, the primary SMTP address, and the password. Then, select Next.

  7. You may receive the following prompt:
      Allow this website to configure <[email protected] server> settings?

    In this prompt, select the Don't ask me about this again checkbox, and then select Allow.

Step 11 - Perform a Selective Startup (advanced users)

When you start Windows normally, several applications and services start automatically and then run in the background. These applications and services can interfere with Outlook. A Selective Startup or "clean boot" process can help you identify problems that are caused by application conflicts.

If you use the Selective Startup option in System Configuration, you can turn services and startup programs on or off individually to check whether the problem occurs the next time that you start your computer. In System Configuration, if you select a check box, the related service or startup program runs when you restart the computer. If the check box is cleared, the service or startup program does not run when you restart the computer.

Follow this procedure to use the process of elimination to identify the problem in Windows 10, Windows 8, Windows 7, or Windows Vista.

How to do a Selective startup

  1. In Control Panel, select System and Security, select Administrative Tools, and then double-click System Configuration.

    Note

    If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.

  2. Select the General tab, select Selective startup, and then clear the Load system services and the Load startup items check boxes.

  3. Select the Load system services check box, select OK, and then select Restart.

  4. If the problem reoccurs after you restart the computer, do one or both of the following tasks, as necessary.

    To determine which system service is causing the problem

    1. In System Configuration, select the Services tab, select Disable all, select the check box for the first service that is listed, and then restart the computer.

      Note

      If the problem doesn't reoccur, then you can eliminate the first service as the cause of the problem.

    2. With the first service selected, select the second service check box, and then restart the computer.

    3. Repeat this process until you reproduce the problem.

      Note

      If you can't reproduce the problem, you can eliminate system services as the cause of the problem.

    To determine which startup item is causing the problem

    1. In System Configuration, select the General tab, and then select the Load startup items check box.

    2. Select the Startup tab, select Disable all, select the check box for the first startup item that is listed, and then restart the computer.

      Note

      If the problem doesn't reoccur, you can eliminate the first startup item as the cause of the problem.

    3. While the first startup item is selected, select the second startup item check box, and then restart the computer. Repeat this process until you reproduce the problem.

Step 12 - Create a Windows user profile (advanced users)

Your user profile is a collection of settings that let you customize the computer appearance and performance. It contains settings for desktop backgrounds, screen savers, sound settings, and other features. User profiles help make sure that your personal preferences are used when you log on to Windows.

To determine whether this problem is caused by a corrupted user profile, create a user profile to see whether the problem still occurs when you use the new profile.

How to repair a corrupted user profile in Windows 8

Step 1 - Create a user account

To create a user profile, you must first create a user account. When the new account is created, a profile is also created.

  1. Swipe in from the right edge of the screen, and then tap Search. (If you are using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then select Search.) Type Command Prompt in the search box, right-click Command Prompt, and then select Run as administrator.

    Note

    If you're prompted for an administrator password or for confirmation, type the password or provide confirmation.

  2. Type net user UsernamePassword /add, and then press Enter.

Step 2 - Copy old files to the new user profile** After you create the profile, you can copy the files from the existing profile

Note

You must have at least three user accounts on the computer to complete these steps. This includes the new account you just created.

  1. Log on as a user other than the user that you just created or the user that you want to copy files from.

  2. In Control Panel, select Appearance and Personalization, and then select Folder Options.

  3. Select the View tab, and then select Show hidden files, folders, and drives.

  4. Clear the Hide protected operating system files check box, select Yes to confirm, and then select OK.

  5. Open File Explorer. To do this, Swipe in from the right edge of the screen, and then tap Search. (If you are using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then select Search.) Enter File Explorer in the search box, tap or select Apps, and then tap or select File Explorer. Type Command Prompt in the search box, right-click Command Prompt, and then select Run as administrator.

  6. Locate the C:\Users\Old_Username folder, in which C is the drive that Windows is installed on, and Old_Username is the name of the profile that you want to copy files from.

  7. Select all the files and folders in this folder, except the following files:

    • Ntuser.dat
    • Ntuser.dat.log
    • Ntuser.ini
  8. On the Edit menu, select Copy.

    Note

    If you don't see the Edit menu, press Alt.

  9. Locate the C:\Users\New_Username folder, in which C is the drive that Windows is installed on, and New_Username is the name of the user profile that you created earlier in this method.

  10. On the Edit menu, select Paste.

  11. Log off, and then log back on as the new user.

Note

If you have email messages in an email program, you must import your email messages and addresses to the new user profile before you delete the old profile. If everything is working correctly, you can now delete the old profile.

If you have used Outlook before, at some point you must have come across issues like Outlook not responding, stuck at “processing,” stopped working. Also, it may freeze or hang. This might become overwhelmingly frustrating for some users and can also affect corporations enormously. In this post, we will discuss the causes and solutions to resolve these issues. According to Microsoft, these issues could be due to one or more of the following reasons:

  • Safe termination of Outlook in case of software hang
    Sometimes when you try to close Outlook it doesn’t shut off in the first attempt; hence you persistently try to quit the program several times which causes the hang. In this scenario, you can run the ‘Task Manager’ and select Outlook and hit ‘End process.’run the ‘Task Manager’ and select Outlook
  • Opening Outlook in safe mode
    There is a high chance that the Add-ins are causing the Outlook to run abnormally. It is then recommended to run Outlook in safe mode. To access safe mode, you should hold the CTRL key and left-click the Outlook icon. When you open the Outlook in safe mode, you will see the safe mode mentioned in the title bar in parenthesis (see below).run Outlook in safe mode
  • Disable your Outlook Add-ins
    In the earlier method, running Outlook in the safe mode might solve the hang issue, but it also disables all the Add-ins at the same time. So, disabling the Add-ins one-by-one might help you to catch the culprit. In this way, you can pinpoint the Add-in which is responsible for these issues. Click File > Options. This will open the Outlook Options Dialog box. In Manage, click Add-ins > Go. This opens another dialog box, which has a list of all the add-ins. You can uncheck/ check the Add-ins one by one to find which add-in is causing the problem. Disable Outlook Add-ins
  • Close all other memory-intensive programs
  • Out of all, MS Outlook is the most complex and memory-intensive program. Due to this constraint, it sometimes freezes or hangs. It is therefore advisable to terminate all the memory-intensive programs before running Outlook on your machine. You can adequately terminate the required program by ending it via Task Manager, as explained earlier.

  • Repair Outlook data files
  • Outlook comes with an inbuilt repair tool called as Scanpst.exe to repair your Outlook data files (.PST or .OST) if damaged. In order to run this repair tool, you need to close the Outlook first. For Office 356Outlook, 2019 and 2016 Scanpst.exe can be found here-

    (Any version) C:\Program Files\Microsoft Office\root\office16\

    For Outlook 2019 and 2016, it can be found here-

    • (32 bit) C:\Program Files\Microsoft Office\Office15\
    • (64 bit) C:\Program Files (x86) \Microsoft Office\Office15\

    After launching the Scanpst.exe application, you will be asked to choose the Outlook data file which needs to be repaired.

    Inbox Repair Tool

    Next, a popup box will show you the status of the repair process.

    PST Repair Process Complete

  • Disable your anti-virus program
  • Most of the times, it is the conflict between the anti-virus program and add-ins, which causes Outlook to freeze or hang. You can try updating your anti-virus program. If this too doesn’t solve this issue, then try disabling the anti-virus program and check whether Outlook works without any interruptions.

  • Repair your MS office suite
    If you tried all the above methods with no luck, then you should consider this method. In Control panel, click Programs and Features. Select the MS Office suite and click Change.To Repair MS office suite
  • Clicking on Change will open a Dialog box. Choose the appropriate option accordingly.

    Check options for reparing

  • Kernel for Outlook PST Repair
  • If you tried all the above methods with no luck, as a last resort, you should consider using a reliable third-party software such as Kernel for Outlook PST Repair. It can repair large sized PST files as it not limited by file size. You can later save the retrieved PST files in various formats such as DBX, MBOX, etc. User can also Export the recovered PST files to Office 365, web-enabled email services, and Exchange Server. Moreover, it can also recover meta properties of emails such as To, Cc, Bcc, From, Subject, Date, Time, Contacts, Tasks, Calendars, and Journals.

    We have discussed various techniques to resolve the ‘Freeze and Hang’ issues associated with Outlook. Traditional methods might not work in this case; hence, it is advised to try using PST repair tools such as Microsoft’s Scanpst.exe or a reliable third-party tool such as Kernel for Outlook PST Repair. In many ways Kernel for Outlook PST Repair tool is far superior to the Scanpst.exe.

    Outlook freezes or is not responding: What to do

    Microsoft Outlook is one of the most popular email clients in the world. According to a report by Enlyft, Outlook is the go-to email client for companies with $10 million-$50 million in revenue and about 50-200 employees, making it a popular choice for SMBs. Among individual users too, it accounts for about 10 percent of the world’s email market share. Despite this popularity, Outlook can still throw errors, just like any other tool. One of the most common problems is that Outlook freezes or doesn’t respond at all.

    What do you do then? Let’s first quickly understand the possible causes.

    Causes for Outlook freezes

    Here are some possible causes for Outlook not responding:

    • You haven’t installed the latest patches and updates.
    • It is used simultaneously by another process.
    • Some program that you installed or the associated process conflicts with Outlook.
    • An add-in you installed interferes with Outlook’s processes.
    • Your computer is infected.
    • Mailboxes are too big.
    • There are problems with Office programs.
    • Your user profile has become corrupted.
    • ODF files have become corrupted.

    While this is not an exhaustive list, these are some of the most common causes of Outlook failure.

    Solutions when Outlook freezes

    Here are some solutions to fix this rather annoying error.

    Restart Outlook

    As with any tool, the easiest first option is to restart Outlook as this can release unwanted cache and other processes that are deadlocked.

    Ideally, close Outlook and open it in safe mode. You can do this in one of the following ways.

    • If you’re using Windows 10, right-click Start and type Outlook.exe/safe. Press Enter, and this should open Outlook in safe mode.
    • In Windows 7, go to Start, and type Outlook/safe. Press Enter.
    • If you’re using Windows 8, open “Apps,” select “Run,” and type Outlook/safe. Click OK.

    Once your Outlook opens, close it again, open it normally the next time. This should fix Outlook freezes a good deal of the times.

    Install the latest updates and patches

    Another easy fix is to install the latest updates and patches as this can address many of the underlying problems of a freeze.

    To install the latest updates, go to the search box in the Start Menu, and type “Updates.” When a dialog box opens, click the “Check for updates” button and choose “Install updates” on the next screen.

    Wait for the updates to install and restart your PC. Once the system is up, open Outlook and check if any updates are pending for it.

    To check this, Go to File and select "Account" > "Update options" > "Update now." For Office 2010, go to Help > Check for updates.

    If any updates are pending, install them and restart your Outlook.

    Check the system requirements

    Microsoft Outlook requires certain minimum system requirements, so make sure your system has these memory and CPU requirements.

    This will most likely be the issue if you’ve upgraded to a higher Office version on the same computer.

    Repair Outlook

    You can repair Outlook to prevent such freezes. But you can only do it for the entire Office suite.

    • Close all the Office programs.
    • Go to Control Panel and navigate to Programs and Features.
    • Navigate through the list and right-click on Microsoft Office. Choose “change.”
    • Select the “Online Repair” radio button.
    • Click the “Repair” button.

    outlook freezes

    This option repairs all the Office programs. Once it’s done, open Outlook to check if it’s working fine.

    Look for other processes

    Some features such as AutoArchive or syncing from a mobile device reduce the performance of your Outlook simply because these processes consume a lot of resources.

    To know if Outlook is being used by another process, look at the status bar at the bottom of the screen. It’ll tell you the process that’s using Outlook. Either wait for that process to complete before you start using Outlook or stop the other process.

    Repair corrupted Outlook Data Files

    Outlook Data Files, or ODF for short, are files that store all Outlook data such as emails, calendars, contacts, attachments, and more. The files differ depending on which version of Outlook you are using and the types of email accounts you have. They can get corrupted for many reasons and your Outlook won’t work when ODF files are corrupted. You can use the built-in repair tool to fix this problem and if it persists or if the file is corrupted, consider using third-party tools to fix this problem.

    Check your antivirus software

    Sometimes, your antivirus software won’t play nicely with Outlook. The best way to check is to disable your antivirus and see if Outlook works and if it does, you know the cause of the problem.

    Check if your antivirus software is outdated, and if so, update it as this will resolve Outlook connection issues. If the problem persists, reach out to the customer support team of the antivirus tool for a possible solution, provided you know for sure that it interferes with Outlook’s processes.

    Address add-in conflicts

    Though add-ins enhance your user experience, they can also interfere with the working of Outlook. The best way to zero-in on this problem is to disable add-ins and see if Outlook works.

    To start Outlook without these add-ins, open Outlook in the safe mode. If the problem doesn’t persist in the safe mode, the add-ins are probably the cause.

    For a permanent fix:

    • Go to File > Options > Add-ins.
    • Select COM Add-ins and click Go.
    • Clear all the checkboxes in the dialog box.

    Finally, restart Outlook and open it in the normal mode, and it should work fine.

    Repair corrupted user profiles

    User profiles customize the look and feel of a computer or service for you. It has the settings that match your preferences, so you can access them when you log in each time.

    However, this user profile can become corrupted due to many reasons, and this can prevent Outlook from responding. To understand if a corrupted user profile is the problem, create a new user profile and try it. If your Outlook responds well, stick to this user profile and delete the corrupted one.

    To create a new user account:

    • Press Windows + R to open the run dialog box and type cmd to open the Command Prompt. Make sure you have admin privileges. Alternatively, search for Command Prompt, right-click on it, and choose “Run as Administrator.”
    • In the command prompt, type the new “usernamepassword/add.”
    • Once the user profile is created, log in with these credentials.
    • Navigate to C:\users\old_username and copy all the files except user.dat, user.dat.log, and user.ini.
    • Move all the files to C:\users\new_username.
    • Log off and log in again with the new credentials and check if your Outlooks works.

    Reduce your mailbox size

    When your mailbox is too large, it impacts Outlook’s performance. To resolve this issue, move some of the contents in your large folders to separate folders.

    To do this:

    • Navigate to the Folder tab and click “New Folder.”
    • Give a name for the new folder.
    • Select the location for this folder and click OK.
    • Move some of the larger emails and attachments to this folder.

    This folder will be a subfolder but will be in a different location.

    Alternatively, use the AutoArchive option to archive older emails in a safe place.

    Do a clean boot

    When Windows starts normally, many processes and services start automatically and run in the background, and these can interfere with Outlook.

    When you do a clean boot or a selective startup, you can turn on or off the processes and services through a checkbox in System Configuration.

    Note that this option is for advanced users who understand the role of different processes in the system. If you’re unsure, don’t try this option, as turning off some critical services may cause your computer to crash.

    Thus, these are some of the solutions to fix Outlook freezes. If you know the cause of the problem, you can use the related solution. Otherwise, you’ll have to cycle through each solution until your problem is fixed.

    How to Deal with ‘Microsoft Outlook Not Responding’ Error?

    Microsoft Outlook is undoubtedly one of the most versatile email client tools available today, and this is right why it is used worldwide by organizations of all sizes. But like any other software, Outlook is also prone to bugs and problems”10 Common Outlook Problems“

    As a user, these problems can sometimes be frustrating. One common problem that crops up often is “Outlook not responding” or Outlook Not Working error. To help you fix this error and to reduce your frustrations, we have put together a comprehensive article that will give you all the answers to your questions.

    How does this problem affect Microsoft Outlook Users?

    When an application or process gets stuck in operation or reaches a deadlock for resources, the “not responding” message appears on the title bar of the application’s window. This is common across all applications on a Windows machine.  Most of the time, the best option is to wait it out, even it is frustrating for you!

    When this happens to your Outlook, the stakes are much higher because there is always a possibility for you to be in the middle of a conversation with a potential client. Or worse, you could be expecting an update for a crucial security issue and your Outlook stops working.

    When you try to click anywhere on the Outlook window, the entire screen becomes translucent with the message “Microsoft Outlook not responding” displayed on the title bar.

    Frustrating, right? Well, all is not lost and here are some things you can do to fix

    How to Fix the “Outlook not responding” error:

    The below-mentioned solutions work to fix issues in Outlook 2007, 2010, Outlook 2013 and Outlook 2016.

    1. Quit Outlook and all related processes through Task Manager

    outlook not responding

    If an existing Outlook process is stuck in operation, a fresh instance of the application cannot be initiated successfully. This is because one or more ‘outlook.exe’ processes would be running in the memory when you’re trying to start another ‘outlook.exe’ process, thereby creating a conflict.

    Thus, one of the first things to try out is to kill all ‘outlook.exe’ processes through the Task Manager. For this:

    1. Right-click on the taskbar and click on “Task Manager”; you may also open it directly by pressing Ctrl + Alt + Del from the keyboard.
    2. Click on the Processes tab and search for all processes with the word Outlook in their name (primarily, processes named outlook.exe)
    3. For each process you find, select it by clicking on it once and then click on the ‘End Process’ button at the bottom right corner of Task Manager

    This should kill all the Outlook processes. Try restarting your Outlook to see if the issue is fixed. If still your outlook not working, follow the guide below; 

    2. Identify and remove the problematic Outlook add-ins

    outlook not responding

    Add-ins and customization files are installed into Outlook to improve the user experience. However, sometimes, faulty add-ins can cause problems with the normal working of Outlook. Hence, that’s where you should look next.

    Here’s how you can spot if add-ins are creating the issue:

    1. Start Outlook in safe mode by pressing down the Ctrl key and clicking on Outlook icon; you may also launch Outlook in safe mode by opening the command prompt and typing outlook.exe /safe.

    Note:  Launching Outlook in safe mode loads Outlook without any add-ins or customisation files.

    1. If Outlook launches successfully, try to send/receive emails or do any other task to ensure that add-ins are the problem.
    2. To find which add-in is faulty, go to File -> Options -> Add-ins -> Go
    3. Due to the safe mode, all add-ins will be unchecked. One by one check add-ins and keep restarting Outlook with each check. Wherever Outlook doesn’t start correctly, that add-in is your culprit.

    3. Turn off the Antivirus Program

    Antivirus software is meant to safeguard your computer from all threats. Some of the products are designed in such a way that they scan every outgoing and incoming email to your system to detect problems. This might cause problems with the normal functioning of Outlook at times. Plus, your antivirus may flag some add-ins as untrustworthy and could even block them, thereby causing Outlook to hang or crash.

    Go to Control Panel and turn off your antivirus. Restart Outlook and check. If everything works fine, you know where the problem is. To keep using both your antivirus and Outlook without issues, add Outlook and all its add-ins (that you trust) to the list of trusted applications in the antivirus software.

    4. Organize and Archive Stuff

    In order to function smoothly, Outlook needs to be organized and cleaned up every few weeks. So, make sure you organize all emails in separate and properly labelled folders instead of a single huge one. Also, delete all old emails that are no longer required. This also includes emptying the Outlook Deleted Items folder. In addition to these basic steps, you should archive old important emails in order to free up some space within the Outlook data file.

    5. Reduce Outlook Data File Size

    Outlook stores all data in the Personal Storage Table or.PST files. But when used with Exchange mailboxes, the data is stored in OST files (.ost) as well. If your Outlook PST or OST files grow too large in size, they are prone to damage and corruption.

    Outlook not responding

    Hence, clean up your Outlook inbox and other folders, archive old emails, and empty the Deleted Items folder to reduce the size of Outlook data files. Moreover, you can use Outlook Compact feature to compress data files and reduce their size.

    6. Repair & Update Outlook

    Outlook not responding

    If none of the above-mentioned solutions works, there might be an issue with your Outlook installation. To fix such issues:
    a.  Go to Control Panel and find MS Office in the installed programs
    b.  Right-click on it and select Change
    c.  Click on Repair -> Continue
    d.  Follow the subsequent instructions

     

    Once the repair is complete, check for any Outlook service-packs or other updates your installation is missing and if there are any, download and install them. You can also refer to this Manual

    Conclusion

    To conclude, “Microsoft Outlook not responding” or Outlook not working error is not only frustrating but is also cryptic. This means, finding the cause of the problem and its solution is not easy. Try the above resolutions to see which one resolves the issue for you.

    If nothing works, Outlook PST file might have been corrupted or severely damaged. Repair it using a trusted PST repair software called Stellar Repair for Outlook Technician. The product will help you fix issues within the corrupted PST and will also extract all data from it to store in a fresh new PST that you can directly import into Outlook. Apart from this you can Split or compact PST file to avoid the error due to oversize PST File.

    How To Fix Outlook Not Working/Opening in Windows 10

    Hello,

    One of my users is having issues with Outlook freezing constantly and it's driving me mad. It will freeze while typing e-mails and looking through the inbox.

    First I noticed that his OST had reached 5GB which apparently is where you can start to run into performance issues (https://support.microsoft.com/en-us/help/2695805/how-to-troubleshoot-performance-issues-in-outlook), I did a winsat test on the link above and it came back at 3MB/s. 

    I've now upgraded him to an SSD and cloned the HDD to it, the winsat test is now coming back around 250MB/s but the user is still experiencing hangs although I'm sure they're not as bad.

    Other things I've tried now:

    • Disabling ESET (Anti-Virus)
    • Installed all Windows Updates
    • Disabled Add-ins and started in safemode
    • Compacting PST/OST
    • Re-creating profile
    • Turned off typing animations
    • Re-pairing MS Office, full and quick.

    I'm currently in the process of re-creating his profile with the shared mailboxes set to run in online mode to make his OST file smaller to see if that resolves the issue, he's also got a 5GB Archive file (.PST) though.

    I'd greatly appreciate if anyone else has any ideas that I could try or should I just re-build it and hope it makes it better?

    I'd be willing to bet this has much to do with the pst file, I've had similar experiences and almost every time, disconnecting the pst stops the issue, and reconnecting it start up the issue again. For large pst's, first, split them into smaller files, the run a scanpst on each one. That's been the cure for my users. Every time, one of the pst's they had connected, had multiple issues that scanpst took care of and then no more issues.

    If it were me, I'd run either Process Explorer or Process Hacker and check the CPU levels while watching the person work for a few minutes. My guess is it's got some kind of real time updating going on that's hogging Outlook's little slice of processor.  Ifso facto, you can start looking for options that allow for this sort of thing and turn them off until it stops.

    I would suggest this same thing.  SCANPST has worked well for us in the past.

    Additionally, the TeamViewer Outlook add-in has caused serious issues for us in the past.  It's been a culprit in many Outlook crashes, and disabling it or removing it entirely has helped a lot.

    Agree with Edwin. It's not total PST file size, we have some that are giant and we sync all down, not just last year.  it's the amount of items in the default root folders that brings outlook to its knees, and hence the whole system. The root folders being sent, inbox, outbox, deleted, calendar, etc. I had a user with 80,000 in his inbox in outlook 2010ish, exchange 2003. Moving them to subfolders INSTANTLY solved the problem. It was intermittent and getting worse before that. After that, everything ran like a champ. We had tried new hardware, more memory, ssd, everything.

    Relevant articles (can't find the original microsoft article that specifically called out the root folders and that subfolders weren't a big deal):

    I've found that creating a new PST has solved this issue.  Create a new PST, copy over all e-mail, calendar entries, tasks, etc., Make the new file the primary and disconnect the old file.

    OP

    Let's backup with the PST related recommendations. He's on 2016 on O365. He shouldn't have a PST, he should only have an OST. There is no "moving mail around" to a new PST because it's all in the cloud/on the server if on prem. You would just remove the outlook profile under mail in control panel, and set it up again and let it re-download, where it would create a new OST. PST is for offline mail, OST is for cached mail.  By default, there should be no PST here. I've had 5gb PSTs on a decent network no problem. Since he has an archive, you'd just un-attach the archive PST and if it doesn't change things, it's not the PST. It's not active if you detach it. Or, make a new profile, and don't attach the archive.

    Check the item counts in the root folders (not just unread number, select like inbox and look in the lower left for items: xx,xxx. Do that for all the main folders)

    Just checked my own 2016 O365 folder which is set to defaults except downloading all mail, not just the last year. 10GB OST file, 16MB NST file, no PST file. If they have an archive, get it in the mailbox so it's in the database, and then use a company-wide archiving solution/policy/procedure.

    You will also be interested:

    Did you get an Outlook not responding error? Is Outlook stuck on a screen that simply says "Processing"? Or does Outlook freeze or stop working when you're opening a file or sending an email message?

    There are a number of possible reasons for Outlook to behave this way. We've presented the potential solutions in order from quickest to most time consuming.

    Start Outlook in safe mode to fix "Processing" screen

    If Outlook stops responding at a screen that says "Processing," you can close Outlook, start it in safe mode, then close it and open it normally to fix the problem.

    1. Close Outlook.

    2. Launch Outlook in safe mode by choosing one of the following options.

      • In Windows 10, choose Start, type Outlook.exe /safe, and press Enter.

      • In Windows 7, choose Start, and in the Search programs and files box, type Outlook /safe, and then press Enter.

      • In Windows 8, on the Apps menu, choose Run, type Outlook /safe, and then choose OK.

    3. Close Outlook, and then open it normally.

    If Outlook isn't stuck at a screen that says "Processing," or this didn't resolve your issue, continue to the steps below. If those steps don't work, see Need additional help? at the end of this article.

    Step 1: Is there a dialog box open?

    Some things you do in Outlook ask for confirmation. For example, the first time you try to Dismiss All on a list of reminders, Outlook asks you if you're sure you want to do that. If you don't choose an option on that dialog box, Outlook won't let you do anything else. Check for open dialog boxes. Pressing Alt+Tab will help you switch from window to window and help you see what dialog boxes might be stopping Outlook from responding.

    If you can't find a dialog box open, move on to the next step.

    Step 2: Make sure Outlook isn't working on a large or long process

    If you try to delete or move a large number of messages at once, Outlook can appear to freeze, but really, it's working behind the scenes. Check the status bar at the bottom of the screen. If Outlook is performing some operation on hundreds or thousands of messages at once, it might appear to be stuck. Give Outlook a few minutes to finish the process and it should start to work again.

    If Outlook isn't working on a large or long process, move on to the next step.

    Step 3: Install the latest Windows and Office updates

    Outlook works best when it's up to date. We recommend setting Windows Update to automatically download and install recommended updates. Bug fixes, new features, and performance enhancements are released regularly.

    If installing the latest updates didn't resolve your issue, move on to the next step.

    Step 4: Repair your Office programs

    Repairing your Office programs can resolve issues with Outlook not responding or freezing. Errors in Office files are repaired automatically.

    1. Quit any Office programs that are running.

    2. In Control Panel, choose Programs and Features.

    3. In the list of installed programs, right-click Microsoft Office 2016 or Microsoft Office 2013, and then choose Change.

    If repairing your Office programs didn't resolve your issue, move on to the next step.

    Step 5: Repair your Outlook data files

    When you install Office, an Inbox Repair Tool (SCANSPST.EXE) is also installed on your PC. The Inbox Repair Tool can resolve issues by scanning your Outlook data files and repairing errors.

    If repairing your Outlook data files didn't resolve your issue, move on to the next step.

    Step 6: Create a new user profile

    Your profile stores a variety of settings that control how Outlook looks and feels. You can create a new profile and then add your email accounts to the new profile.

    1. Close Outlook.

    2. Choose one of the following:

      • In Windows 10, choose Start. Type Control Panel and press Enter. Choose User Accounts > Mail > Show Profiles.

      • In Windows 8, open the Apps menu, choose Control Panel > Mail > Show Profiles.

      • In Windows 7, choose Start > Control Panel > Mail > Show Profiles.

    3. Choose Add, and in the Profile Name box, type a profile name, and then choose OK.

    4. Enter an email address and a password for the primary email account you use in Outlook and then walk through the steps to create the profile.

    5. Once the profile is created, on the Show Profiles dialog, choose Prompt for a profile to be used.

    6. Start Outlook and choose your new profile.

    If creating a new profile solves your issue, you can return to the Show Profiles dialog and delete your old profile.
