Before you troubleshoot the problem, make sure that your computer meets the minimum system requirement of Microsoft Outlook. There are several methods to resolve this issue, which are as follows:
To investigate possible add-in issues, try opening Outlook in safe mode.
Follow these steps:
If Outlook works and doesn’t crash while composing or sending emails, follow these steps to disable add-ins.
Once add-ins removed, open Outlook and check if it works fine.
Windows updates also bring fixes and security patches for other Microsoft applications such as MS Office. You may also manually check and update Outlook on your PC.
After updating Windows, restart Outlook software and try to access the email folder.
If the above steps do not resolve the issue, try creating a new user profile in Outlook. Then check if it is working fine.
Set up your email account and check if Outlook works without crashing.
There could be a problem with the MS Outlook installation. You can fix this by repairing the MS Office.
If you use antivirus software that includes Outlook integration, you may experience a few performance issues. This may sometimes cause Outlook to crash or stop responding.
Open your antivirus program and disable Outlook integration. Alternatively, you may also disable antivirus temporarily to check if the problem is resolved.
