When sharing documents with your colleagues, it allows you to see what changes are made and by whom. In order to preserve the tracked changes log in a less than full control permissions scenario, the Track Changes and Accept Changes features are disabled for users who do not have "Full control" in the My Permission dialog for the RMS protected document. Track Changes is a useful feature to show any markups or modifications made to a Word document. A Microsoft Word file that contains tracked changes has the changes stored in a log within the file. You will see this behavior when you don't have "Full control" provided by Rights Management Services (RMS) for the user.
Solution: 1) Open the document and save it to a PDF in Word first. The default settings for the 'Publish What' opt for 'Document' and not 'Document showing markup' which are available when saving documents to PDF in Word but not in our add-in. This applies when the RMS is applied to individual documents or when RMS is applied to a SharePoint site library. The convert to PDF option uses the Microsoft Office conversion engine.
The Track Changes control, as well as the Accept and Reject changes controls are disabled. You notice that you cannot use Word's Track Changes feature. You are editing a Microsoft Word document that has Rights Management Services (RMS) applied to it and includes tracked changes.
