On our Office 365 tenant, we have a site with a document library. Is it possible to make some PDF documents not downloadable? So far I'm seeing the answer is no, but I'm soliciting any ideas.
I see View Only permissions only apply to doc types with server-side file handlers. PDF is not one of those as far as I know. Also cannot set Offline Client Availability to No since this should affect only specific documents, not the whole site.
