Microsoft Teams multi-account deadlock blocks all accounts when one fails auth
When one Teams account has a login failure, the app enters a loop trying to authenticate it, blocking access to all other accounts. Removing the broken account is impossible because it requires switching to it first — a catch-22 with no documented workaround. Affects enterprise users managing personal and work accounts simultaneously.
