Collaboration in Microsoft Office is a necessity in the modern day workplace. PowerPoint decks are especially collaborative documents that can require lots of editing over time in preparation for a board meeting, for instance. Once you have a presentation that many have collaborated on, another challenge arises: keeping track of the edits.

There’s a lot of opinions and contributions that can go into a 30+ slide presentation, and to make sure you account for the opinions that matter in a presentation, you can make comments, review comments, and track changes and revisions within a PowerPoint deck to make collaboration easier. See the video above and steps below to do each:

2. Click Comment.
   • A sidebar will appear on the right where you can type out your comments.

Review Comments

1. Select the Review tab.
2. Click Show Comments.
   • A sidebar will appear on the right where you can review the comments made in the presentation.
