Installing or updating the Teams app for education users across supported platforms
Hello, this is Emily.
Can you go to Windows Settings > Accounts > Access Work or School, do you see your wife's work email address there? Or anything about Azure AD? If so, click on that, then click on disconnect. Then restart the computer.
If that's not resolving the issue, I might have a misunderstanding of the issue. To help me understand better, can you please share a screenshot where you encountered the error message? Thank you!
