Viewing a co-authored document

When you are co-authoring a file using Microsoft Office for the web, other users who are editing the file at the same time can view all the edits made by you. Similarly, you can view all the edits made by other users who are editing the file.

However, if you are viewing the file in Microsoft Office for the web using the View option, you cannot view the changes being made to the file. This is because Microsoft does not allow viewing real time changes made during a co-authoring session for users in View mode.
