Sorry to hear that you’re having trouble signing in. To rule out a browser session issue, please clear your browser’s cookies and cached files, then fully close and reopen the browser before trying again. You can also try an InPrivate window in Microsoft Edge, since it starts a fresh session and does not retain cookies or site data after the session ends. If your Microsoft account has a secondary alias, such as another email address or phone number, please also try signing in with that alias instead of the primary one.
Please also test on a different network, such as a mobile hotspot, in case the current connection is contributing to the sign-in problem. If the issue still happens after these tests, the next step is to use Microsoft’s Sign-in Helper, which can help identify whether the account is locked, verification is failing, or the username is no longer being recognized.
I’ll be waiting for the results to continue helping you.
