Deleting Documents
Deleted documents are kept in the recycle bin for 90 days. If you wish to recover a deleted document, ensure you go to the recycle bin before the 90-day window is up.
To delete a document, you can either select the check mark next to the document and find delete from the top menu bar of the SharePoint site, or select the ellipses next to the document and select delete from the menu that appears next to the document.
Recovering Documents (Recycle Bin)
You will find your recycle bin in your left-hand menu of OneDrive.
In the Recycle Bin, locate the document you lost, click on it, and click restore. The document will live in the Recycle Bin for 90 days before it is permanently deleted. If you would like to permanently delete the document, select delete to permanently delete it from the recycle bin.
You can also perform bulk actions on deleted documents such as restore or delete for multiple options at once. To do this select the checkmark next to each document then select your action.
