Outlook Keeps Crashing on Startup

Outlook keeps freezing or crashing whenever you launch it. This happens with most users at least once. But don’t worry, if this is troubling you, you can try opening Outlook in Safe Mode. Here’s how to do it: 

• Press the Windows Start button.

• In the given field, type outlook /safe, and hit the Enter button. 

• If this works, disable add-ins one by one in File > Options > Add-ins to identify the culprit. 

If running Outlook in Safe Mode doesn’t resolve the issue, try repairing Outlook via Control Panel: 

• Press the Windows button. 

• Type “control panel” in the search bar, and open it. 

• Choose “Uninstall a program” under Programs.

• From the list, look for Microsoft 365. 

• Once you find it, right-click on it and select “Change.” 

• Click on Yes, then select the radio button next to Quick Repair. 

• Next, click on Repair. 

• Wait a few moments while the program is being repaired. 

• Once it is finished, click “Close” and check if the issue is fixed. 

Sometimes, using an outdated version of Outlook can also cause crashes at startup. So you must update the program regularly. Follow these steps to update Outlook: 

• Open Outlook on your computer.

• Click on “File.” 

• Select “Office Account.”

• Click on Update Options, then select Update Now.

• Wait while Outlook checks for updates and installs them.

• Once the installation is done, restart Outlook and check if the problem is resolved.
