Users can check back in a document that is locked for editing so that another user can open and edit it. This can be used, for example, if the user who has a document locked for editing is out of the office.
From a Documents list, click the Document being edited icon to see the name of the user currently editing the document.
The Stop Editing pop-up displays the name of the person who has the email locked.
After clicking Stop Editing, the changes made by the previous user will be synced and saved back to FYI.
