Cannot open PDF from SharePoint

On a number of occasions customers have asked me why they cannot open Acrobat PDF files in their browser from a SharePoint 2010 document library. When the URL for the PDF file is clicked, the browser only gives two options: ‘Save’ and ‘Cancel’.
There is no option given for ‘Open’ to open the document straight away.

This is not a client setting (which was my first thought).

There a setting in the General Settings of the Web Application that handles security headers when documents are opened in the browser. By default, this is set to ‘Strict’.

Changing this to ‘Permissive’ will give the users the option to open the document straight from the browser.


Please note: whether the PDF opens in the browser or in a separate Acrobat clientapp is still a client setting 🙂
