Hi Kartik, all Firstly, a great thank you! to all who made this possible. It is a big leap forward after almost 2 years of anxious waiting for it to happen 😊. I have run some tests and got it working with all the latest downloads as you have documented it. One thing, though, was that I needed to set the EnablePDFv2Protection = True advanced property in the AIP policies. I haven't found that hint in your description – should it work without this setting? Another - much more worrying - finding was that PDF files protected with SharePoint 2016 or SharePoint Online IRM protection can still not be opened with Adobe Reader. While I am aware that this is "old style" document protection it is still in use and fully supported afaik. Do you have any plans in making this work as well with Acrobat Reader DC? Thanks -dani
