How to Delete and Restore Files in OneDrive
If you have an item you no longer need in OneDrive for Business, delete it. Deleted files can be restored if you change your mind later.
A dialog box appears asking you if you’re sure you want to delete the item.
It may take a few seconds, but the file is transferred to the Recycle bin.
If you have deleted an item and later realize that deleting that item was a mistake, you can retrieve it from the Recycle bin.
The file is restored to the Documents library.
