My Outlook got hacked now cant read emails

The symptoms strongly indicate the account is still compromised and the attacker is manipulating how messages appear. Treat this as an active security incident and secure the Microsoft account first, then clean up Outlook settings.

Follow these steps in order:

1. Secure devices
   • On every PC/phone/tablet used to sign in to Outlook.com, run a full antivirus/malware scan.
   • If using Windows 10/11 or 8.1, turn on and run Windows Defender as described in the guidance:
     • Select Start → search for Windows Defender → open it and run a full scan.
   • Do this before changing any passwords.
2. Reset Microsoft account security
   • After scans complete, change the Microsoft account password using the official flow: change your password.
   • Choose a strong, unique password as described in the strong password guidance.
   • If sign-in fails, use the official reset flow: reset your password.
   • Enable multi-factor authentication (for example with Microsoft Authenticator) once access is restored.
3. Use the official hacked/compromised-account helper
   • Go to the official helper for hacked or compromised accounts and start the guided flow: Start.
   • Provide the account email/phone and follow the steps; it will direct to the right recovery and security actions.
4. Check and clean Outlook.com account settings After regaining secure access, sign in to Outlook on the web and review:
   • Rules: Delete any suspicious inbox rules that might be altering or redirecting messages.
   • Forwarding: Remove any unknown forwarding addresses using the Outlook.com forwarding settings.
   • Automatic replies: Turn off any automatic replies the attacker may have set.
   • Also review connected accounts and remove anything not recognized.
5. If the account is blocked or behavior persists
   • If Outlook.com shows the account as blocked due to unusual activity, use the Sign-in Helper to unblock: Sign-in Helper.
   • If unblocking or recovery fails, use the “When you can't sign in to your Microsoft account” path linked from the unblock article for further support.
6. Ongoing protection
   • Review the Outlook.com security tips in “Help protect your Outlook.com email account” and “Phishing and suspicious behavior in Outlook” to avoid future compromise.
   • Monitor recent sign-in activity and sign out of all sessions from the Microsoft account security page.

If, after completing these steps (including rules/forwarding cleanup), messages still appear visually corrupted, capture screenshots and contact Outlook.com support using the “How to get Outlook.com support” link referenced in the unblock article so support can review the mailbox and display behavior.
