Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
If the account is locked, the main self-service path is to sign in at https://account.microsoft.com and request a security code to unlock it.
Key points:
- Any phone number that can receive text messages can be used for the security code. It does not need to be linked to the account.
- The code expires after 10 minutes.
- If the code does not work, enter the numbers from the body of the text message, not the header.
- If "usage limit exceeded" appears, the phone number may have been used too many times in a short period, or the number was flagged as suspicious.
If the sign-in page does not show a Next option, the account may be locked for suspicious activity or a Terms of Use violation. In that case, use the aka.ms/ link shown in the lock screen and submit the account reinstatement form. After submission, a Microsoft Online Safety support agent reviews it and contacts by email. Do not submit additional requests, because that can slow the response.
If the account is still blocked after 3–4 days:
- Check the inbox, junk, and spam folders for the email address used for the reinstatement request.
- If another verification method is available, try that method instead.
- Try a different network, such as switching between Wi‑Fi and mobile data.
- If repeated verification attempts were made, wait at least 24 hours before trying again. In some cases, waiting longer can help.
- Use the sign-in helper to identify the available recovery path.
If access to security info was lost:
- If the password is known but not all security methods are available, sign in to Advanced security options, add a new way to sign in or verify, confirm it with a code, then remove the old method.
- Do not change all security info at once, because the account may be restricted for 30 days.
- If access to all security info is lost, select I don't have any of these during sign-in and follow the replacement process. After replacement, there is a 30-day wait before sign-in is allowed.
- If the password is not known and no security info is available, use the account recovery form.
Support can help route the issue, but support agents cannot send password reset links or change account details for a locked Microsoft account.
