We have started adding the capability to see who changed what in PowerPoint Online. When you return to a document where collaborators made changes while you were away, you will see a notification as well as some details about what changed. For additional history, you can try the Version History feature under File>Info>Version History. Let us know if this helps!

Please give PPT and Excel the same capability as word to redline and make edits. It's currently impossible in PPT (just comments), and Excel's editing process is very clunky.Pat supported this idea ·
