Unlike Word, PowerPoint does not provide a Track Changes reviewing option. If you would like to track changes in a presentation, you should have the reviewer review a working copy of the presentation and then compare the two presentations.
This feature works the same in all modern versions of Microsoft PowerPoint: 2010, 2013, and 2016.
It may be useful to set, in that copy, the reviewer's user name by selecting File > Options, and then on the General tab, under Personalize your copy of Microsoft Office, setting these options.
When the file has been reviewed:
- Open the reviewed file.
- Select the Review tab, and in the Compare group, select Compare.
- From the dialog box, locate the original copy, select it, and click Merge.
- The Comments and Revisions panes will open on the right, showing changes and any inserted comments.
- Select the revisions and you will see them noted in the presentation.
- Right-click the revision icon and select Accept Change to keep the change.
- Save the file to save the changes that were made.
Discarding Changes from Specific Users
You can reject a specific user's changes when comparing the two files.
To reject a user's changes:
- In the copy reviewed by that person, from the Review tab, select Reject and then select Reject All Changes to the Presentation.
- When you are done comparing the copies, select End Review from the Compare group.
- If you are sure all changes you want to make have been saved, select Yes in the pop-up that is displayed to end the review.
As you are reviewing the changes to the document, you can also manage comments.
To manage comments:
- In the Comments pane, click the X to delete a comment.
- You can respond to comments and add new ones by clicking New and adding your comment.
- Navigate through the comments using the Previous and Next arrows.
