Collaboration Features in PowerPoint 2016
With the software update in the summer of 2016, Microsoft revealed several enhanced collaboration features that appear when you are working on a PowerPoint presentation with other users.
The improved collaboration features in PowerPoint 2016 still allow users to share their presentations. Users are also still able to collaborate in real time using OneDrive or SharePoint. In addition to those features, users are now also able to view the name of everyone working within the document and the areas of the document they are working on. Users can also bounce around ideas, offer suggestions, or chat with the other collaborators on your presentations instantly by using Skype for Business.
Buttons in the top-right corner of the ribbon allows users to access these new features and view all document activity.
