Unknown Pdf's in my One Drive Folder

Because you don’t own the file, OneDrive won’t let you delete it—so dragging it to the recycle bin won’t work.

If the file appears suspicious or inappropriate, you can report it.

On the Microsoft OneDrive website, sign in and go to the Shared section. If you can find the file there, right-click it and select “Report a concern.” Choose the appropriate reason, add any relevant details, then submit the report.

If the file doesn’t appear in Shared, or if you’d rather not sign in, you can report it using Microsoft’s anonymous Report Abuse form by submitting the file link.
