That thread started back in 2011 so maybe there are some more details that someone knows. &nbsp;There is a difference between someone breaking a data protection policy as it is as simple to do as 'Prt Scr' from some of the most secure systems in the world, but that is about company policies. &nbsp;I would have thought that as the file is hosted on the Sharepoint site that it should be possible to only allow editing on the SharePoint site.
