Hello @Dennis McCorkle
As you mentioned, you are trying to switch between your Work and Personal accounts in Microsoft Teams on your Android phone, and you keep receiving error AASTS90023 even after reinstalling the app and clearing the cache.
To better understand your situation, please help check the following:
(Since this situation is urgent for you, you can temporarily try accessing Teams through a web browser on your mobile using private (incognito) mode while the root cause is being identified.)
- When the error appears, does it happen immediately after entering your email, or after entering your password or completing verification?
- Do you have other Microsoft apps installed (such as Outlook, OneDrive, or Authenticator) that are signed in with the same account?
If you still need my assistance, please come back with screenshots or any additional details so I can review it again and see if there’s anything more I can help you with.
Kind regards,
