Thanks for reaching out to the Microsoft Q&A forum Support.

If I get you correctly you are getting an error code while adding account on Teams free. I sincerely apologize for the inconvenience you have experienced.

Here are some recommended troubleshooting steps to try out

1. Check Network Settings:
   • Disable any VPN service.
   • Try switching to a different network (e.g., mobile hotspot or another Wi-Fi).
2. Clear Credentials and App Data:
   • On Android: Go to Settings > Security & Privacy > More > Encryption & Credentials > Clear Credentials.
   • On iOS: Remove saved Microsoft accounts from Settings > Passwords & Accounts.
   • On Windows: Clear Credentials:
     1. Press Windows + R, type control keymgr.dll, and press Enter.
     2. In the Credential Manager, go to Windows Credentials.
     3. Locate and remove any entries related to Microsoft Teams
     Clear App Data:
     1. Close Microsoft Teams completely (right-click the icon in the system tray and select Quit).
     2. Press Windows + R, type %appdata%\Microsoft\Teams, and press Enter.
     3. Delete all contents in the folder.
     4. Repeat for these additional folders:
        • %localappdata%\Microsoft\Teams
        • %appdata%\Microsoft\Teams\Cache
        • %appdata%\Microsoft\Teams\Service Worker\CacheStorage
     5. Restart your computer.
     6. Open Microsoft Teams and sign in again with your account.
3. Try logging in from a different device or web browser.
