Hi, I'm John!
To help narrow down the issue:
- Are you using Outlook on the web or the Outlook desktop/mobile app?
- Is this a personal Microsoft account (Outlook/Hotmail/Live) or a work or school account?
In the meantime, please check these folders where older emails may have been moved:
- Archive
- Deleted Items
- Junk Email
- You can also try using the Search bar and type keywords from the email or document you are looking for.
Also note that if emails were deleted more than 30 days ago, they usually cannot be recovered unless they were stored in another folder or backed up.
Let me know what you see on your end.
