Hi Meily,

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

Based on the error message “657rx” that you received, this typically means that Microsoft is unable to recognize your account credentials. This can happen for several reasons. I’d like to guide you through a few steps that may help you sign in successfully. These steps are easy to follow and tailored to your situation.

You can try the following steps to clear your credentials cache to ensure a clean reset

Please sign out your accounts from Office applications, then close all Office applications. 
Open File Explorer, paste the following path, and delete all files and folders. %localappdata%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy 
In the Windows search bar, search for "Access Work or School". 
Check if you can see your school account in "Access Work or School". 
If you don't see it, please select Connect and add your business account.

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

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 business account and Office apps. 
Select and remove those entries. 
Restart your computer and try adding your account in Office again.

Download OLicenseCleanup.vbs and run it. In this way, you can use this package to remove the license, clear the stored identities in the registry, and remove the credentials. You can follow this: Reset activation state for Microsoft 365 Apps for enterprise - Microsoft 365 Apps | Microsoft Learn to reset activation state

Restart your device.

Reopen Office apps and sign in with the correct account.

I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this.

Thank you for your patience and your understanding. If you have any questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.

I look forward to your thoughts on this.
