For macOS, you can try this: the Keychain cleanup is the key step (that’s the rough equivalent of deleting OneAuth on Windows).

That's not working... I have cleaned every file in Keychain that was and is related to MS. I have deleted the app, removed caches, and removed files, but the issue persists. The only thing I need to do is to wipe my entire computer and start fresh!!

  What You Can Try Next
  1. Run a credential cleanup script like the one below to aggressively remove Teams-related Keychain items:
  security delete-generic-password -s 'OneAuthAccount'
  security delete-generic-password -l 'Microsoft Teams Identities Cache'
  security delete-generic-password -l 'com.microsoft.adalcache'
  # ...and other relevant entries as your setup requires
  2. Create a brand-new macOS user profile, reinstall Teams there, and test to see if the old account still appears.
