Can you programmatically determine if modern comments are enabled in Word?
If it is not possible to check this directly [I don't think it is], is there any property of a comment that you can check that will indicate whether it was added or edited using modern comments? It would need to include comments that were originally added in the old style, but then edited using modern comments.
Try to use the
Countsproperty of theCommentscollection:Use the Comment.Range property which returns a
Rangeobject that represents the contents of a comment. For example:See Redesigned Word Comments VBA deprecation announcement for more information.
