Hi @Nick Janney,

Thank you for posting your question in the Microsoft Q&A forum.  

Based on the error message you received “The credential is invalid. Unexpected sub status (6008) and Error 657rx”, this typically means that your account credentials are not being recognized by Microsoft.

I’d like to guide you through a few steps that can help you get signed in smoothly. These steps are designed to be easy to follow and tailored to your situation.  

You can try the following steps and then check if it still happens or not.   

1. Please sign out your accounts from Office applications, then close all Office applications.   
2. Open File Explorer, paste the following path, and delete all files and folders. %localappdata%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy   
3. Go to settings > Accounts > Access work or school
4. Check if you can see your school account in "Access Work or School".   

If you can see it, please select it and select Disconnect. After that, please click "Connect" and log into your business account again to register the device.   

1.  Clear Cached Credentials   
   • Open the Control Panel on your PC.   
     • Go to User Accounts → Credential Manager.   

• Under both Windows Credentials and Generic Credentials, look for any entries related to your Microsoft 365 account.   
• Select and remove those entries.   
• Restart your computer and try adding your account in Office again.   

Fully remove cached licenses and account data: 

Download OLicenseCleanup.vbs and run it. In this way, you can use this package to remove license, remove cached identities in HKCU registry and remove credentials. For more details, you can refer to this article: Reset Microsoft 365 Apps for enterprise activation state.  

• Reboot your device. 
• Reopen Office apps and sign in with the correct account.
