How to get back your account?

If a Microsoft account was hacked and the attacker changed the email address and password, the supported recovery path is:

1. Start with the Microsoft account hacked-account recovery flow and use the sign-in helper tool.
2. Before changing or resetting the password, run a full malware scan on the PC:
   • Open Windows Security
   • Go to Virus and threat protection
   • Select Scan options > Full scan > Scan now
3. After the scan:
   • If sign-in is still possible, change the password.
   • If sign-in is not possible, use Reset your password or Recover your account.
4. If prompted for verification, follow the security code steps in the recovery flow.
5. If recovery succeeds, review account settings such as connected accounts, forwarding, and automatic replies.

Important facts:

• The sign-in helper tool is the main starting point for most Microsoft account sign-in problems.
• Microsoft support agents are not allowed to send password reset links or access and change account details.
• If the account remains inaccessible after the self-help recovery steps, use Contact Microsoft Support for the available support options.
