OneDrive has a recycle bin and a second stage recycle bin. A deleted file can be found
in the recycle bins up to 3 months after deletion unless the file(s) were purged from
both recycle bins.
Once logged in, click the App Launcher in the top left and select "OneDrive".
Click "Recycle Bin" from the navigation menu on the left. If you do not see the file in the recycle
bin, scroll to the bottom of the list, and click the link to "Check the Second stage recycle bin".
Click the circle to the left of each file you wish to restore to select them.
Click "Restore" from the menu at the top of the page to restore the file(s).
