Constant Error Code under school account.

Question

Hey!

I've been trying to sign in through my school given outlook account and an error code keep popping up. I'm unable to use excel, teams, and other applications because of this. What could be the issue? Would love some guidance on what to do because it's hindering my ability to be productive.

Answer 1

Have you tried signing in through your school's Microsoft 365 website? If the error keeps showing up across Excel, Teams, and other apps, it could be an account or school license issue. You may need to contact your school's IT support to check your account. If you share the exact error code, it may be easier to figure out what's wrong.

Answer 2

Hi Taven,

I’m sorry you’re having trouble signing in to your school account, especially since this is preventing you from using Microsoft Teams, Excel, and other applications.

As a first check, please try signing in to Microsoft 365 through an InPrivate or Incognito browser window using your school account.

If you’re able to sign in successfully through the browser but the desktop applications still don’t work, please sign out of all Microsoft 365 applications, close them completely, restart your device, and then sign in again.

If the issue continues after trying these steps, could you please share the exact error code or a screenshot of the error message you’re seeing? This will help me better identify what is causing the sign-in issue and provide troubleshooting steps that are specific to your situation.

Warm regards.

Answer 3

Clear the cached Microsoft 365 credentials and re-register the school account in Windows, because this is the documented resolution for error 657rx, “credential is invalid,” sub-status 6008, across Office desktop applications.^1^

Clear and reconnect the school account

These instructions apply to Windows:

1. Sign out of Teams, Excel, Outlook, and every other Office application, then close them completely.
2. Open File Explorer, enter this path in the address bar, and press Enter:

      %localappdata%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
   

3. Delete the files and folders inside that folder.
4. Open Settings → Accounts → Access work or school.
5. Select the school account and choose Disconnect.
   • If this is a school-managed computer, ask school IT before disconnecting it because the account may be used for device management.
6. Select Connect and sign in again with the school account to re-register it.
7. Open Control Panel → User Accounts → Credential Manager.
8. Check both Windows Credentials and Generic Credentials. Remove entries associated with the affected school or Microsoft 365 account.
9. Restart Windows, open one Office application, and sign in with the school account.^2^

If error 657rx remains

On Windows 10 version 1703 or later with Microsoft 365 version 1807 or later, repair the Microsoft Entra Web Account Manager (WAM) plug-in:

1. Right-click Start and open Windows PowerShell (Admin).
2. Run:

if (-not (Get-AppxPackage Microsoft.AAD.BrokerPlugin)) {
    Add-AppxPackage -Register `
      "$env:windir\SystemApps\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\Appxmanifest.xml" `
      -DisableDevelopmentMode -ForceApplicationShutdown
}
Get-AppxPackage Microsoft.AAD.BrokerPlugin

3. If the command completes without errors and returns package information, restart the computer and test Excel or Teams again. Microsoft documents this repair for organizational-account authentication failures caused by missing sign-in package information.^3^

Separate a device problem from a school-account problem

Try signing in to Microsoft 365 through a browser:

• Browser works, but desktop apps fail: the account itself is active; continue with the device-local steps above. If necessary, run the Microsoft 365 sign-in troubleshooter by opening Get Help, searching for sign in to Microsoft Office, and following its prompts.^4^
• Browser sign-in also fails: contact the school’s Microsoft 365 administrator. Ask them to verify the account is enabled, reset the password if necessary, and check its Microsoft 365 license and sign-in policies. For a forgotten or rejected school-account password, Microsoft directs non-administrators to their administrator or the work/school self-service password reset process.^5^

When contacting school IT, provide 657rx, sub-status 6008, code 2148073520, and the timestamp—but do not post your email address, tenant ID, correlation ID, or other account identifiers publicly.
