Hello,

I am providing support for a user who is on Windows 11 Professional. He has an intermittent issue where Outlook disconnects every two hours. He's using 3 email addresses in the same Outlook application and the same in Teams. I wanted to keep only the organization's address and remove the other two, but they keep coming back.

I tried uninstalling Office and Teams, but it didn’t work. I also tried disconnecting the two accounts and unlinking them from Windows, but that didn’t work either.

I attempted to remove the cache, but I’m not sure if I did it correctly.

My question is: how can I remove all traces of Outlook, Teams, OneDrive, etc.? I want to completely remove them and reinstall everything to keep only a single account.

Outlook | Windows | Classic Outlook for Windows | For business
