I have read multiple posts that are very similar to my problem, but none are the fix I need. I have a document that has gone back and forth several times with tracked changes without any issues. The last draft I received back has all comment boxes with no name other than "author". When I make revisions or add a comment box, it lists my name and the tracked changes are in a different color but when I save the document, it all reverts to the same color and "author" in the comment boxes. I have verified that the track changes color setting is varied "by author". I have gone into the Trust Center Settings and found that the "remove personal information from file properties on save" is NOT checked BUT it is also greyed out so it can't be checked/unchecked. I am assuming that this last editor used Document Inspector to remove personal information and that is why when I save the document my information goes away.

So my question is, how do I get it to save personal information (show different authors names and revisions) from this point forward?

Also, I am working in Microsoft 365 (I wasn't given that option to select when I registered).
