Try below steps to check and fix:

 

1. Check Shortcut Integrity
•    Right click the Outlook icon in the Start Menu or desktop → More > App settings.
•    If available, select Reset.
•    Alternatively, delete the shortcut and recreate it: 
o    Search for Outlook in the Start Menu.
o    Right click → Pin to Start or Pin to Taskbar.
2. Run Outlook in Safe Mode
•    Press Win + R, type: 

outlook.exe /safe


•    If it opens, the issue may be caused by an add in. Disable add ins under File > Options > Add ins.
3. Clear Cached Profiles
•    Go to Control Panel > Mail > Show Profiles.
•    Create a new profile and set it as default.
•    This rules out a corrupted Outlook profile.
4. Repair Office Installation (Full Repair)
•    Go to Settings > Apps > Installed Apps > Microsoft Office (or Microsoft 365).
•    Choose Modify > Online Repair (not Quick Repair).
•    This reinstalls core components without removing your data.
5. Check Windows Updates
6. Reinstall Outlook
•    If none of the above works, uninstall Office/Outlook and reinstall.
