Q: I am able to login to Teams on the browser, but received an error signing in to desktop app below:
Sorry, but we're having trouble signing you in.
Message: AADSTS51004: The user account ________== does not exist in the 5ba5ef5e-3109-4e77-85bd-cfeb0d347e82 directory. To sign into this application, the account must be added to the directory.
A: Clear Teams cache and signing out Windows work and school account.
- 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.
- Go to File Explorer, and type in %appdata%\Microsoft\teams.
- Once in the directory, you’ll see a few of the following folders:
- From ‘Application Cache’, go to Cache and delete any of the files in the Cache location. “%appdata%\Microsoft\teams\application cache\cache”
- From ‘Blob_storage’, delete any files that are located in here if any. “%appdata%\Microsoft\teams\blob_storage”
- Within ‘Cache’, delete all files “%appdata%\Microsoft\teams\Cache”
- Within ‘databases’, delete all files “%appdata%\Microsoft\teams\databases”
- Within ‘GPUCache’, delete all files “%appdata%\Microsoft\teams\GPUcache”
- Within ‘IndexedDB’, delete the .db file “%appdata%\Microsoft\teams\IndexedDB”
- Within ‘Local Storage’, delete all files “%appdata%\Microsoft\teams\Local Storage”
- Lastly, from ‘tmp’, delete any file “%appdata%\Microsoft\teams\tmp”
- After the steps, disconnect the account.
- At the end, restart the machine and try to sign in to Teams again.
