Update File in Office Online | Communifire Documentation

You can edit Microsoft Office files in Office Online. Users can work on the same document at the same time. If a file is checked out, only the user who checked it out can edit the file in Office Online. To allow simultaneous editing, don't check out the file before editing. Changes are saved to File Version History after the document is closed by all users.
