My account has been hacked and deleted by the hacker or changed username, how could I retrieve my account?

For a hacked Outlook.com/Microsoft account, only the official recovery process can be used. The options depend on whether the account still exists and whether the username/security info were changed.

1. If the account is hacked but still exists
   1. First, secure your devices:
      • Run a full antivirus/malware scan on every device used to sign in to the account.
      • On Windows 10/11 or 8.1, turn on and run Windows Defender as described in the guidance for hacked accounts.
   2. Try to sign in and immediately change the password:
      • If sign-in is still possible, go to your Microsoft account and change the password to a strong, unique one.
      • Then review account settings for malicious changes (connected accounts, forwarding, automatic replies) and remove anything you do not recognize.
   3. If you cannot sign in:
      • Use the official hacked-account troubleshooter and Sign-in Helper. It will ask for your email/phone and guide you through self-help or connect you to support options.
      • If prompted, use the Microsoft account recovery form and provide as much accurate information as possible (old passwords, recent activity, etc.).
2. If the hacker changed the username or security info
   • If the username or aliases were changed but the account still exists, the Sign-in Helper and hacked-account guide are still the only supported paths.
   • If the security information (recovery email/phone, 2FA methods) was replaced and the automated recovery form cannot verify ownership, there is no alternative manual override for consumer Outlook.com/Microsoft accounts. Support cannot bypass these automated checks.
3. If the account was deleted or inactive
   • If the account has not been signed into for more than two years, it may have been deleted and cannot be reopened.
   • If the hacker deleted the account and it no longer exists in Microsoft’s systems, it cannot be restored via support; a new account must be created.
4. When the system says the account does not exist
   • If you see messages like “We couldn’t find an account with that username” or “account doesn’t exist,” use the Sign-in Helper tool as directed.
   • If the helper and recovery form both fail and report that the account does not exist, there is no supported way to retrieve that specific account.
5. Additional steps
   • Inform contacts that the account was compromised so they can ignore suspicious emails.
   • For linked services (for example, Minecraft, Xbox, or other apps), contact their respective support channels to see if they can help with account linkage separately from the Microsoft account itself.

In summary, recovery is only possible through the official hacked-account and sign-in helper workflows. If those tools cannot locate the account or verify ownership—especially after a username/security-info change or deletion—the account cannot be recovered.
