    I’ve got this login loop after I logged in with me private MS account in Teams. I stucken in a login loop when I tried to log with my company account in Teams. Close your Teams application and go to $HOME//Library/Application Support/Microsoft/Teams in files browser and delete/move the Teams folder to Teams_old for example.

     

    Start your Teams application, the Teams folder will created and the Login window appears.

     

    For me it works, when I delete the $HOME//Library/Application Support/Microsoft/Teams folder after I was logged in with me private MS account.

Referred following link and the issue seems to resolved for good for me.
https://www.uvm.edu/it/kb/article/clearing-teams-cache/

Its a 5 step process:
1. Fully close Microsoft Teams.
2. Copy and paste the following into the Go to Folder box, then click Go:
~/Library/Application Support/Microsoft
3. Right click the Teams folder, then click Move to Trash.
4. Using Spotlight Search (accessed by clicking the magnifying glass on the macOS menu bar), enter “Keychain” and select Keychain Access. Search for Microsoft Teams keys in keychain. Within Keychain, search for “Microsoft Teams” to find the Microsoft Teams Identities Cache entry. Right (two finger) click this item and select the delete option, then close the Keychain Access app.
5. Relaunch Microsoft Teams. You should now be prompted to sign back into Teams.

    Just encountered this same loop of never ending login prompts. I followed the steps above and the issue has resolved itself. Thank ARBattase, thank you for sharing.

    This worked for me - thanks! I was getting very frustrated and removed as many cache files and keychain entries as I could find - but it wasn't until I deleted that Microsoft Application Support file that I could finally close TEAMS and login with a new username. Thanks!

    Thanks very much! The tip about deleting the folder ~/..../Teams solved the problem for me!  Of course, the infinite loop where you cannot enter a different account is a Teams bug, which Microsoft should have fixed already.
