8 Ways to Fix Microsoft Outlook Crashing on Windows

Although Microsoft Outlook is one of the most feature-rich email clients out there, it’s not without its problems. Outlook for Windows can occasionally trouble you with strange errors and abrupt app crashes.


If you are experiencing the same, here are some solutions for fixing Outlook app crashes on Windows.


1. Restart Microsoft Outlook

This may seem basic, but restarting Microsoft Outlook can help resolve any minor issues the app may be experiencing while running. Hence, you should start with that.

To close Outlook on your computer:

  1. Right-click the Start icon and select Task Manager from the list.
  2. In the Processes tab, select Microsoft Outlook.
  3. Click the End task button at the top.
    Close Microsoft Outlook

Reopen Microsoft Outlook after this and see if it works alright.

2. Start Outlook in Safe Mode

Opening Outlook in Safe Mode allows you to use the app without any add-ins. This can help you determine whether the issue is caused by an add-in or something else.

To open Outlook in Safe Mode:

  1. Press Win + R on your keyboard to open the Run dialog box.
  2. Type Outlook.exe /safe in the Open field and press Enter to open Outlook in Safe Mode.

If Outlook works fine in Safe Mode, one of the add-ins is most likely to blame. To find the problematic add-in, you’ll have to disable all of them and then enable them one at a time. Here’s how you can go about it.

  1. Open Outlook in Safe Mode.
  2. Click on File and then Options.
  3. In the Outlook Options window, switch to the Add-ins tab.
  4. Click the Go button next to COM Add-ins.
  5. In the COM Add-ins dialog, uncheck all the add-ins and click OK.
  6. Restart the Outlook app and enable your add-ins one at a time until you find the one causing the problem.

Hardware acceleration is a handy feature in Outlook that allows the app to perform specific tasks more efficiently. This feature, however, can occasionally fail to function as expected, especially if you’re using Outlook on old hardware. If that’s the case, Outlook may crash unexpectedly on your computer.

To check for this possibility, you can disable hardware acceleration in Outlook and then try to use the app. Here are the steps for the same.

  1. In Outlook, click the File tab and then head to Options.
  2. In the Outlook Options window, navigate to the Advanced tab.
  3. Under the Display section, check the box that reads Disable hardware graphics acceleration.
  4. Click OK.

You can try updating the Outlook app on your computer and see if that improves the situation.
