Use the Document Inspector to remove hidden data
To show all changes and comments, click the Review tab on the ribbon, and click All Markup on the Tracking group. All comments that were inserted remain in the document until deleted. All the revisions that were made to a document while the Track Changes feature was turned on remain part of a Word document until they are accepted or rejected. Avoid unintentionally distributing hidden information, such as the document author and names that are associated with comments or tracked changes, by removing hidden data.
