I have to keep shutting down and reopening MS Outlook when using email. It only seems to work briefly before it shuts down again. I've tried reopening in safe mode, but the problem perists. Other friends are having similar problems today. What should we do?

If you have any POP email accounts, this is a know bug.

Temp fix is to uninstall the Jan 2026 Update KB5074109. If you can not uninstall this update thru normal means, see this thread for alternatives.

    If MS Outlook keeps crashing, there are several steps you can take to troubleshoot the issue:

    1. Check for Updates: Ensure that you have the latest updates installed for Microsoft Outlook. Sometimes, bugs are fixed in newer updates.
    2. Investigate Add-Ins: Exit Outlook and start it in safe mode by using the command Outlook /safe. If it works fine in safe mode, the issue may be caused by an add-in. You can disable add-ins by going to File > Options > Add-Ins, selecting COM Add-ins, and unchecking them.
    3. Repair Office: You can repair your Office installation. Go to Control Panel > Programs and Features, find Microsoft Office, right-click it, and select Repair.
    4. Run Diagnostics: Use the Microsoft Support and Recovery Assistant (SaRA) to diagnose and fix issues with Outlook. This tool can help identify problems and suggest solutions.
    5. Create a New Profile: If the issue persists, consider creating a new Outlook profile. Go to Control Panel > Mail > Show Profiles, and then add a new profile.
    6. Check Antivirus Software: Ensure your antivirus software is up-to-date and not conflicting with Outlook. Sometimes, outdated antivirus can cause issues with email clients.

    If multiple users are experiencing the same problem, it may also be worth checking if there are any known outages or issues with the email service provider you are using.
