There's an error when logging in on Microsoft teams - [657rx]

Hi @Arnie Fuentes,

Good day! Thank you for reaching out to Microsoft Q&A forum.

To better understand your situation and assist you appropriately, we’d appreciate your input on the following points:

• Are you accessing Teams via the web version or the desktop application? Are both affected, or just one? 
• Could you please attach the photo that you mentioned?

In the meantime, you can try these suggestions below:

1. Sign out and clear local data

• Sign out of all Office apps and close them completely
• Open File Explorer and go to:

%localappdata%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy

• Delete all files and folders in this location.

2. Re-register your device

• In the Windows search bar, type Access Work or School.
• If your business account is listed, disconnect it and reconnect.
• If not listed, click Connect and add your account again.

3. Clear Cached Credentials

• Open Control Panel > User Accounts > Credential Manager.
• Under both Windows Credentials and Generic Credentials, remove any entries related to your Microsoft 365 account.

4. Try logging in again

• After these above steps, try to restart your computer.
• Open any Office app (e.g., Word), sign in with your account, and check if Teams now works.

I hope this helps you get the assistance you need quickly and effectively.
