Thank you for reaching out to Microsoft Q&A Forum. I’m sorry this happened, getting your account hacked and having emails deleted can be extremely stressful. And you did the right things by regaining access and securing the account.
Just to confirm, could you let me know approximately when were the emails deleted? Recovery chances are strongest the sooner you try.
In addition, here's what you can try:
1. Check Archive or other folders
- Check all folders (including Archive, Junk Email, and custom folders)
- If found, move them to the correct folder.
2. Check Deleted Items & Recoverable Items
- Sign in at Outlook on the web via https://outlook.live.com
- Go to Deleted Items folder
- If the emails aren’t there, select Recover items deleted from this folder at the top and restore anything you recognize. (if available).
- If the emails are still within Microsoft’s retention window, they should appear there.
3. Review Inbox Rules
- In Outlook on the web, go to Settings > Mail > Rules/ Forwarding
- Look for any rules that move, delete, archive, or forward/redirect messages.
- Disable/remove anything you didn’t set up
For more details, you can also see Recover and restore deleted items in Outlook - Microsoft Support
If you don't see anything to recover, please let me know and I'll guide you further. Thank you so much for your time and understanding.
