Managing personal Outlook.com account settings, security, and privacy
Hi, @andy zilveti
Sorry for this unwanted situation. Hackers often hide email in folders people rarely open. In Outlook.com, look in the left folder list for folders like RSS Feeds, Conversation History, Notes, or any folder you don't remember making. If you find your emails there, select them, right-click and choose Move > Inbox.
Next, go to Settings > Mail > Sweep. Sweep rules are kept separate from regular rules, and they can quietly delete or move mail. Remove any you don't recognize. While you're in Settings, open Mail > Junk email too and check Blocked senders. If your friends or family were added there, their emails will never reach you.
For your contacts, if you've ever had this email set up on your phone, open the phone's Contacts app. Your contacts may still be saved there, and you could re-add or export them from the phone.
It's also a good idea to make sure the hacker can't get back in, because changing your password doesn't always kick them out. Go to https://account.live.com/consent/Manage and remove any app you didn't approve. Then, in your Microsoft account security settings, use Sign out everywhere and remove any app passwords.
If you also use the Outlook program on a Windows PC, close it, press Windows key + R, type outlook.exe /cleanserverrules and press Enter. This removes all your mail rules, including any the hacker made. Your own rules will be deleted too, so you'll need to set those up again.
Hackers sometimes create a hidden rule you can't see in Settings. If your emails keep disappearing after all of this, Outlook.com support will need to remove it for you.
Hope this helps!
