Frequently Asked Questions

Why does my old email still show up after deleting it from Windows 11?

You may have residual authentication tokens cached on your system. You can clear these by going to the Windows Credential Manager in the Control Panel and removing any entries associated with the old email, as well as clearing your browser's autofill data.

Will removing an email from my device permanently delete my Microsoft account?

No, selecting 'Delete account from this device' in Windows Settings only removes local access to that email. Choosing 'Close account' from the Microsoft website will permanently delete it, so be sure to select the correct option.

How do I remove an account directly from the Microsoft Authenticator app?

Open the Microsoft Authenticator app on your mobile device, tap on the account you want to remove, tap the gear icon (Settings) in the top right corner, and select 'Remove account'.
