- Check whether the account is in a security info change pending state. On the Microsoft account Security page, if Your security info change is still pending appears:
- Select cancel this request only if the change was initiated by the legitimate account owner and access to the existing security proofs is still available.
- Select let us know if the change was not made by the legitimate account owner. Microsoft states that when all security info is removed, the account can be placed in a restricted state for 30 days, and this process cannot be expedited unless the request is canceled.
- If access is available to Manage how you sign in, remove any alias that is not recognized. Only remove aliases that are confirmed not to belong to the legitimate account owner.
- Review the account’s Recent activity page and expand each sign-in item. If unfamiliar successful sign-ins or unusual activity appear, change the password immediately and update security settings.
- Go to Security settings and update security information so verification methods point only to trusted methods. If possible, add stronger verification such as two-step verification.
