We've rolled out a new, more modern comments experience in the current versions of PowerPoint including our mobile and web versions. This new experience improves collaboration by adding a number of new capabilities to the commenting experience.
Note: For our enterprise customers this feature is turned off by default. If you're an IT Administrator looking for information on how to enable it see What IT Admins need to know about modern comments in PowerPoint.
Let's take a look at what's new.
In the new experience, comments are anchored to objects so if you move the object, the comment goes with it. This makes it easier to see specifically what part of a slide the reviewer is commenting on, and more reliable if you reorganize your content later.
Using comment anchoring is simplicity itself. Just select the object on the slide that you want to comment on and then select Comment or @Mention from the Review tab of the ribbon, or from the right-click context menu, or from the floating toolbar that appears when you've selected an object.
You can type your new comment in the comments pane at the right and select Post (or press CTRL+Enter on Windows, or CMND + Enter on Mac) to finish your comment.
Once the comment is posted you can drag the comment bubble anywhere within the object you commented on to indicate specifically what you're referring to.
Comments in the margin or the comments pane
In PowerPoint for the web you'll find comments in the margin, to the right of your slides, by default. If you want to access all of the features of modern comments you can open the Comments Pane. To turn on the comments pane, click the Comments button towards the top right corner of the PowerPoint window.
Improved @Mentions in comments
This feature is only available to business and enterprise customers.
One you've started your new comment you can call the attention of one or more of your colleagues by using the @mention feature. Simply type the @ symbol followed by their name or email alias.
Tip: The email alias is that part of their email address before the @ sign. For example: "alexw" is the email alias for firstname.lastname@example.org.
When you finish, and post your comment, anybody that you've @mentioned in that comment will get a notification email. The notification email lets them know you mentioned them, and gives them a preview of the slide where the comment happened, as well as the comment you left. They can reply to your comment from the email, or they can click a link in the notification email to open the slide deck and go straight to the comment you left, if they want to see more context.
Resolve comment threads
Comments in files generally represent questions, ideas, or concerns about the content. When those have been addressed, modern comments allow you to mark that thread as resolved. Resolved comment threads won't appear in the margin (though you can still find them in the comment pane) so you can focus on the comment threads that still have open issues.
Increased confidence by design
A modern comment can only be edited by the person who created it.
We're just getting started with improving our comments experience. Watch this space for more new and exciting features to help make your collaboration richer, more secure, and easier.
Why don't I see it?
It may be that you're using a build of PowerPoint that hasn't received these new features yet.
Also, these new comments will only be available to customers using current versions of PowerPoint including PowerPoint for Microsoft 365, PowerPoint for Android, PowerPoint for iOS and PowerPoint for the web. Customers using a channel that gets feature updates less often, like Semi-Annual Enterprise Channel, won't see the feature for a few more months.
If you're using older versions of PowerPoint you won't be able to read or create modern comments. If you receive a file that has modern comments in it, and you have PowerPoint 2010, PowerPoint 2013, PowerPoint 2016, or PowerPoint 2019, you'll get a notification prompting you to open it in PowerPoint for the web to review the modern comments.
If you're using a work or school account it's possible that your IT administrator hasn't enabled the modern comments for you. You may want to reach out to them and ask them if they can turn it on.
