Hi. Thank you for coming to the forum. My name is Femi. It is worth noting that this is a user community, and we are all users here, much like yourself. While we strive to assist and share insights, we are not Microsoft directly.
I am sorry you are unable to sign into Surface Hub. As a user, I understand how frustrating that can be. Rest assured I will try to provide you with a solution.
We’ll need more details regarding your issue to assist you more efficiently. Below are some questions that may help us isolate the issue you are experiencing.
According to the article in https://learn.microsoft.com/en-us/surface-hub/troubleshoot-teams-sign-in-surface-hub "If you can't sign in to Microsoft Teams on Surface Hub, several recommended troubleshooting steps are described on this page.
"First, make sure your Surface Hub is running the latest updates. To learn more, see the following video: How to verify a Surface Hub is fully updated (https://youtu.be/rxL5cUS_3TA
)
Check Microsoft Teams is updated to the latest version. On Surface Hub, open Microsoft Teams, select … > Settings > Check for updates.
Use the Azure sign-in logs (
https://learn.microsoft.com/en-us/azure/active-directory/reports-monitoring/howto-troubleshoot-sign-in-errors#troubleshoot-sign-in-errors-using-the-sign-ins-report) for insights into sign-in errors. You can filter by the Surface Hub device account and look for any failures.
If you still can't successfully sign in to Teams, you can create a support request
