Outlook is Closing Randomly

Hi,

Your Outlook issue happens because the app doesn’t fully close and leaves a background process stuck, often due to corrupted profiles, add-ins, or sync conflicts. Killing the task in Task Manager is only a temporary fix.

Permanent solution:

Update Office and Windows

Repair Outlook (Quick Repair or Online Repair)

Disable problematic add-ins

Create a new Outlook profile

Repair data files with ScanPST

Run Microsoft’s Support and Recovery Assistant: https://aka.ms/SaRA-OutlookDiag

These steps address the root cause and prevent recurrence. I hope this helps!
