Do you have suggestions for the PowerPoint team?
Do you have an idea for a feature that'll make PowerPoint easier to use? One that'll help you make your presentations more compelling? Or even one that'll get you out of the office and on the way home to your family and friends an hour earlier?
Or is there some bug or bad design feature that makes your blood pressure rise every time you use PowerPoint?

Choose File | Feedback or Help | Feedback to send a report that will reach the developers and program managers at Microsoft.
Once you've sent feedback, you may (depending on Office version) see a link to Microsoft's Feedback Hub, where you can view other similar feedback comments and upvote the ones that are important to you.
While you won't get direct feedback from Microsoft in response to your suggestions, they do take them very seriously. The suggestions that get the most votes are the ones that are most likely to appear in upcoming Office updates.
