This error started showing up in some folders inside a PST for a user - "This message is processed by a demo version of DataNumen Outlook Repair so the actual contents are replaced with this information". I can't find much information on the Internet, just that it's expensive and some have found it to not work exceptionally well, especially for the price. Can someone tell me where it came from? Would the user have had to download and install it? I don't see it installed on the workstation. Or is it some back-end piece of Office? Thanks!
