Managing personal Outlook.com account settings, security, and privacy
The behavior shown matches a compromised Microsoft account scenario where the sign-in alias may have been changed. The supported recovery path is:
- Start with the Microsoft hacked-account recovery flow and use the Sign-in Helper.
- If the sign-in page says the account is not recognized or does not exist, use the Sign-in Helper tool.
- The tool can guide through self-help steps and, in some cases, offer the chance to talk to an agent.
- If the account was hacked, secure the PC before changing any passwords.
- Open Windows Security.
- Go to Virus and threat protection.
- Select Scan options > Full scan > Scan now.
- Run the full scan before changing passwords.
- If access is regained, immediately change or reset the password.
- If sign-in works, use Change password.
- If sign-in does not work, use Reset your password.
- Review account security activity if access is restored.
- Go to Security basics.
- Select Review activity.
- For activity that was not recognized, select This wasn't me or Secure your account.
- If two-step verification was turned on and none of the alternate verification methods are accessible, there is no supported recovery path through support agents.
- Support agents are not allowed to send password reset links or change account details.
- If the original username now returns “account does not exist,” check the exact spelling and then use the Sign-in Helper.
- If the account has not been signed in to for more than two years, it may have been deleted and cannot be reopened.
- If more help is needed, use Contact Microsoft Support through the public support flow.
- Support can route to the best support option, but cannot directly reset the password or change account details.
