Answer 1

Since you didn’t specify which account type you’re using, I’ll provide a solution for school account managed by your school. If you’re using a personal account type (@hotmail, @outlook.com, @gmail...), please let me know so I can give you more accurate guidance.

Hi @Nordeen, Naomi E,

Thank you for reaching out to Microsoft Q&A Forum.

Typically, when you sign in to your computer with a school profile, your account is automatically connected to the device. In this case, cached credentials from the previous setup remain in the system, which can cause conflicts. Because you’re affected by your school-managed account, this creates a complex issue that cannot be resolved at the end-user level. Your IT administrator will need to perform several advanced steps to properly reset and configure your profile.

Given the nature of the problem, the most effective next step is reach out to your IT admin to ask them to submit a support request through the Microsoft 365 Admin Center on your behalf.

This route ensures that a Microsoft support engineer can initiate a remote session to investigate backend configurations, run advanced diagnostic tools, and, if necessary, escalate the case to specialized teams with access to internal systems and logs. These backend resources are essential for resolving issues that go beyond what’s visible in the user interface.

I sincerely recommend your IT admin create a support ticket from Microsoft 365 Admin Center > Support > Help & Support.  

Microsoft also provides customer service phone numbers based on your region. You can find the appropriate contact number here: Customer service phone numbers - Microsoft Support 

 

As community moderators, we’re here to guide you, but due to privacy and security limitations, we don’t have access to the backend tools required for a full resolution. For this reason, contacting Microsoft Support via the Admin Center is the most secure and efficient way forward.

 

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 continuing the conversation.

Answer 2

The error message you are encountering, which states "The credential is invalid. Unexpected sub status (6008)," typically indicates that there is an issue with the credentials being used to access your Microsoft account on desktop applications. Here are some steps you can take to resolve this issue:

1. Check Credentials: Ensure that you are using the correct username and password for your school account. You can verify this by logging into the web version of the service, which you mentioned works.
2. Password Expiration: If your password has expired or been changed recently, you may need to update it in the desktop application as well.
3. Re-enter Credentials: Try re-entering your credentials in the desktop application. If prompted, ensure that you are entering the same credentials that work in the web browser.
4. Account Permissions: Check with your IT department to ensure that your account has the necessary permissions and is not disabled or restricted in any way.
5. Clear Cached Credentials: Sometimes, cached credentials can cause issues. You can clear these by going to the Windows Credential Manager and removing any stored credentials related to your Microsoft account.
6. Network Issues: Ensure that your network connection is stable and that there are no firewalls or security settings blocking access to Microsoft services.
7. Update Applications: Make sure that your Microsoft applications (like OneDrive and Office) are updated to the latest version, as updates can fix bugs and improve compatibility.

If the problem persists after trying these steps, consider reaching out to your school's IT support for further assistance.
