User getting refresh token expired due to inactivity in Outlook desktop AADSTS70008

[cmiarshvac]

I have a user who continues to receive this AADSTS70008 error in Outlook Desktop.  This computer has been in service for several years and Outlook desktop has been running fine.  User can successfully authenticate in MS Teams and Outlook on the Web. MFA is enabled.  I have attempted a restart but Outlook produces the same error.  I have seen older posts suggesting that the registry key for the office activation be removed to fix this issue.   Any thoughts on a more straightforward fix than registry hacks?

Please try follow:

1. Clear Cached Credentials

2. Ensure latest update of Office

3. Recreate Outlook profile

4. Check Account default setting if Multiple Accounts

5. Check Time and Date Settings

A repair of the Office installation fixed the issue. But these steps were a good start.
