Does removing comments also remove the replies attached to them?
Yes. A comment and its replies form one thread, so removing the parent removes the thread. Remove replies individually first if you want to keep the original comment.
Which presentation formats can comments be removed from?
PPT, PPTX, PPS, POT, PPSX, PPTM, PPSM, POTX, POTM and ODP.
Are comments actually deleted from the file, or just hidden?
They are removed from the presentation and are not recoverable from the saved file — which is the point when a deck is being prepared for people outside the organisation.
Can I remove comments from one author only?
Yes. Comments are grouped by author, so a single author’s comments can be removed while the rest of the review history stays intact.
