Hi!
As a background, I have this Document Library in SharePoint Online containing PDF files that are supposed to be confidential files wherein the users can only view the pdf documents, restricting the Printing, Copying of Content and Saving/Dowloading.
As a workaround, this PDF files are password encrypted and toolbars and menu bars are hidden by default. That's why I need to open it using the local client PDF Adobe Reader. Since if through the browser, the pdf file security enforced becomes useless with the Save and Button buttons visible and Browser Menu Bar can directly be accessed.
My problem is how do I enforce that PDF files stored in a Document Library in SharePoint Online be opened directly in local client PDF Adobe Reader without asking the users to Disable the Adobe PDF Reader add-on of their browser IE because we have no control over if they follow it or not and also this will also depend on the type of browser used by the user.
Why is it that this Library Settings option in SharePoint Online does not work "open documents in the local client application"?
Please your solution to this would be greatly appreciated.
Thanks,
Venus
