Hi! Let me help you with this issue.

Please click the Start Menu, then type Outlook.exe /safe and press Enter.

And then check if you can close Outlook with no issues.

Relaunch Outlook and try closing it again.

Answer 2

If Outlook 365 is not closing properly and requires you to use Task Manager to shut it down, there are a few troubleshooting steps you can take:

1. Investigate Add-Ins: Sometimes, add-ins can cause Outlook to hang. You can start Outlook in safe mode by pressing Windows + R, typing Outlook /safe, and pressing Enter. If Outlook closes properly in safe mode, you may need to disable add-ins one by one to identify the culprit.
2. Repair Office: You can try repairing your Office installation. Go to Control Panel, select "Uninstall a program," find your Office installation, right-click it, and choose "Change" followed by "Online Repair."
3. Run Outlook Diagnostics: Use the Classic Outlook Connectivity troubleshooter to identify and fix issues. Make sure you are using the same Windows device that has Outlook installed and that it is running Windows 10 or later.
4. Create a New Outlook Profile: If the issue persists, creating a new Outlook profile might help. Go to Control Panel, click on "Mail," then "Show Profiles," and add a new profile.

These steps should help resolve the issue of Outlook not closing properly.
