Accessing Microsoft Teams using organizational or personal credentials
I had been able to use the teams app on my phone, but then went on maternity leave and when I came back i couldn't use the app. we (IT department and I) tried everything on this thread and nothing worked for me. (Meaning, we tried: power on/off, re-install, update phone, update app, re-install on airplane mode, etc... the solutions listed in this thread) What finally did work: while i was on mat leave, i had removed the passcode from my phone. I re-instated the passcode, and Teams started working again. Could be luck/coincidence but worth a shot!
