Changing between multiple Microsoft Teams accounts within the app or browser
I gave up on Teams. It does not work on the mobile phone. Maybe you have an IT department that can look into mobile application?
I'm sorry.

Hi
I’m sorry to hear that the issue with Teams on your mobile phone is still persisting. For the time being, Ihope you can use the Teams web version to continue your work, and please feel free to reach out to us again if you need any further assistance.
Teams is the worst.
I have my wor account and an account that I have been added to due the completion of building app.
The error occurs after I type login and password and then several screens flash as it looks to be switching,
Then their code appears and nothing happens. You must restart the program from beginning only to get the
Save result every time.
Thank you for your update. I have reviewed this case again to support you.
Since you have already tried repair, reinstall, and clearing all cache, the issue is unlikely to be caused by the mobile device itself.
The error AADSTS90023 means Azure AD cannot validate the sign-in request. This typically happens when the authentication token is invalid, mismatched between organizations, or does not meet requirements such as MFA or Conditional Access.
In this scenario (switching accounts or accessing another organization), the behavior usually indicates a service-side authentication issue, rather than a local app problem.
At this stage, it is recommended to:
If others are not affected, the issue may be specific to the account. If multiple users are affected, it is very likely related to organizational settings.
As a workaround, Teams Web can be used, as it generally handles these authentication scenarios more reliably than the mobile app.
If you encounter any difficulties while working with the admin and need further assistance, please let me know so I can try to provide you with more information.
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.)
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,

Good day @Dennis McCorkle
Just checking in to see how things are going with your issue.
Please let me know if I can do anything more for you.
Stay safe and happy!
NONE of anything your AI bot is sharing works to get me logged into TEAMS. How can I speak a human?
The repair did not work. The reinstall did not work. I cleared all cache from browser and phone also. I still receive the error code and cannot login into account on the mobile phone.
