I've got a document library in which I've given some users "Restricted View" permissions since we need to block printing and downloading. I've confirmed that the documents in the library inherit their permissions from the document library. When these users open a Word or Excel file it works fine:
but opening a PDF gives this:
Like I said, there are no specific permissions set on the documents themselves. And looking at the access on each document shows these people have "Restricted View" permission on all these files.
I set up a test user with the exact permissions of these users and logged in as that test user in Chrome Incognito mode as well as Internet Explorer. I can open both the PDFs and Office files without any problem.
I noticed in the preview pane it was complaining about IRM:
What's weird is that I just looked in the library settings and IRM is turned off.
The real question is why is IRM in play here at all... Any better ideas?
