account was hacked, details changed, cant get help

Use the Microsoft sign-in helper first. It is the primary path for hacked or blocked Microsoft accounts and can either guide through self-help or offer the chance to talk to an agent.

Recommended order:

1. Start the sign-in helper: Start
2. If access to the PC used with the account is still available, run a malware scan before changing any password:
   • Open Windows Security
   • Go to Virus and threat protection
   • Select Scan options > Full scan > Scan now
3. If sign-in is still possible anywhere, go to Security basics and review recent activity:
   • Select Review activity
   • For activity that is not recognized, choose This wasn't me or Secure your account
   • Then select Change password
4. If sign-in is no longer possible because the attacker changed the sign-in details:
   • On the sign-in page, select Forgot my password
   • Then select I think someone else is using my Microsoft account
   • Follow the recovery steps
5. If Outlook.com is blocked because of unusual activity, use the unblock flow: Sign-in Helper
6. If the recovery path keeps failing, use Microsoft Support: Contact Microsoft Support Enter the problem and select Get Help, then Contact Support.

Important limits:

• Support agents are not allowed to send password reset links or access and change account details.
• If the attacker changed the account’s sign-in and recovery information, recovery must still go through the official recovery and sign-in flows.

If the account now shows as not linked to the original email, that matches cases where the sign-in information was changed. The supported next steps are the sign-in helper, password recovery flow, recent activity review if any session still works, and Contact Support.
