I note that the wonderfully helpful article here on how to "Maggie" a corrupted document (https://answers.microsoft.com/en-us/msoffice/forum/all/how-can-i-fix-a-corrupt-document-whats-a-maggie/b18bf177-6300-4ab5-b9c9-77a0148a24a1)
includes instructions only for saving a document that does not include tracked changes. It uses Word's Copy and Paste functions.
But for those co-writing or editing a document who are working with Track Changes and Comments, the way to Maggie a document is to use Word's Spike function, not Cut and Paste. In Windows, this would go something like this:
- In the corrupt document, turn Track Changes off
- Ctrl+a
- Shift+Left Arrow
- Ctrl+F3 (to spike)
- Ctr+z (to reverse the spike's deletion)
- In a new blank document, make sure that Track Changes is turned off, choose the appropriate Design style from the Design tab and
- Ctrl+Shift+F3 (to spike the old document with Track Changes into the new document)
- F12 (to save to a new file)
Voila! All your tracked changes and comments are now there, along with a (hopefully) usable version of the document.
