Answer 1

Dear @Nguyễn Hữu Thịnh,

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

I understand you’re currently unable to sign in due to the error message: “The credential is invalid. Unexpected sub status (6008)” along with code 2148073494. This typically means your device is trying to authenticate using outdated or corrupted sign‑in information.

To better assistance, could you please confirm following information

• Does this issue happen in all Microsoft apps or only in specific ones?
• Is this a work/school account (e.g., ******@company.com) and do you know if your license is active?

Are you signed into Windows with the same work account, or a different/personal account?

Does it happen when you use other device to sign-in the same account?

In the meantime, I recommend some steps below

Step 1/ Sign out of all Office/PowerPoint/Teams apps.

Step 2/ Clear cached authentication data:

Delete contents of this folder: %localappdata%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy

Open Control Panel > Credential Manager > Windows Credentials and remove any Microsoft/Office‑related credentials.

Step 3/ Go to Settings > Accounts > Access work or school, disconnect your work/school account, restart the device, and reconnect it.

Step 4/ Try signing in again to confirm credentials are valid.

Note: Please understand that as a forum moderator, my role is to provide general guidance and troubleshooting support. I don’t have access to internal systems or backend tools, and I appreciate your understanding of these limits.

I hope the information shared helps point you in the right direction. Please try the steps above and let me know if they work. If not, we can continue working together to narrow this down.

The first response may not always resolve the issue right away, but with your help and more details, we can work toward a solution.

Thank you for your patience and understanding. I'm looking forward for your reply.

Answer 2

To resolve the issue with your Microsoft Teams account where you receive the error message "The credential is invalid. Unexpected sub status (6008)," you can follow these steps:

1. Check Your Credentials: Ensure that you are entering the correct email address and password associated with your Microsoft Teams account.
2. Clear Cache and Cookies: If you are using the Teams web client, try clearing your browser's cache and cookies or use an incognito/private browsing window.
3. Reinstall Teams: If the issue persists, consider uninstalling and reinstalling the Teams application. This can help resolve any underlying issues with the app itself.
   • Uninstall Teams from your device.
   • Delete the Teams folder located in the %appdata%\Microsoft directory.
   • Download and install the latest version of Teams.
4. Check for Account Issues: If your email is linked to both personal and work accounts, ensure that you are using the correct credentials for your work account. You may need to unlink the accounts if they are causing conflicts.
5. Contact Support: If none of the above steps work, consider reaching out to Microsoft support for further assistance, especially if you have a specific Correlation Id and Timestamp that can help them track your issue.

Following these steps should help you resolve the credential error you are experiencing with Microsoft Teams.
