Thank you. 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. Your emails will remain safe.

    Hi Dave,

    Do you have an Exchange account in the New Outlook? It seems to be an issue.

    I’m eager to hear back and work together to find a solution.
