AADSTS50020 can't login to teams account

Got invited by friend, then decided to setup my own teams. SO after being removed from his organization my teams stopped working. MY office365 still working correctly

Error: Sorry, but we’re having trouble signing you in.

AADSTS50020: User account 'piotr.w.cierkosz@gmail.com' from identity provider 'live.com' does not exist in tenant 'PrismCode' and cannot access the application '5e3ce6c0-2b1f-4285-8d4b-75ee78787346'(Microsoft Teams Web Client) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.

Hi piotrcierkosz, It seems that the error message is a Azure AD login error. This article give a explanation of the issue: http://www.agilepointnxblog.com/windows-azure-active-directory-login-error-aadsts50020/. It recommends you delete your Teams client cache as the following steps: 1. Fully exit the Microsoft Teams desktop client. To do this, either right click Teams from the Icon Tray and select ‘Quit’. Or run Task Manager and fully kill the process. 2. Go to File Explorer, and type in %appdata%\Microsoft\teams. 3. Once in the directory, delete any file in the following folders: %appdata%\Microsoft\teams\application cache\cache %appdata%\Microsoft\teams\blob_storage %appdata%\Microsoft\teams\Cache %appdata%\Microsoft\teams\databases %appdata%\Microsoft\teams\GPUcache %appdata%\Microsoft\teams\IndexedDB %appdata%\Microsoft\teams\Local Storage %appdata%\Microsoft\teams\tmp If it is no luck after that, you could uninstall and reinstall the Microsoft Teams client and have a try.
