A tool for managing user identities, credentials, and access across on-premises and cloud environments
If the sign-in name now shows an unfamiliar @msaccsafety.com address, the account’s sign-in alias or security info was likely changed during the compromise. The supported recovery path is:
- Run a full malware scan on the PC before changing anything:
- Open Virus and threat protection
- Select Scan options > Full scan > Scan now
- Use the Microsoft account hacked-account recovery flow and sign-in helper. It can guide to self-help steps or offer the chance to talk to an agent.
- After access is restored, immediately change or reset the password.
- Review account settings that attackers commonly change:
- Connected accounts
- Forwarding
- Automatic replies
- Check the account’s recent activity page to review unusual sign-ins and security challenges.
- Add or update security info so recovery does not depend on attacker-controlled details. Microsoft recommends adding another way to sign in or verify, such as updated security info or Microsoft Authenticator.
If the account is blocked, unblocking requires a password reset. If that still fails, use the Microsoft sign-in help path that includes password reset guidance and support contact options.
If the account is locked and the “Let’s prove you’re human” option does not appear, use the reinstatement link shown in the sign-in window and submit the form. After submission, wait for the Microsoft Online Safety review email and do not submit multiple requests.
Deleting the account directly is not a supported recovery step in the provided guidance. The documented path is account recovery, password reset, security review, and, when offered, agent contact through the official support flow.
