Managing personal Outlook.com account settings, security, and privacy
Thanks, I completely missed it :)
Please try this, and let me know if it works, my community colleague suggested that in a Reddit thread and it worked.
Try this, please.
Press Windows + R, type %localappdata%\Microsoft, and press Enter.
Delete the Olk and OneAuth folders.
Restart Outlook.
This only removes temporary Outlook data that will be recreated automatically. Please try reconfiguring the account and let me know.
I’m eager to hear back and work together to find a solution.
