Just installed March 2017 CU for SharePoint 2016. Now users can't open PDFs. When clicked in a library, Adobe Acrobat opens with the error There was an error opening this document. This file cannot be found. Meanwhile, the browser directs the user to the Word Online which opens the PDF.

If I go directly to the PDF, i.e. http://example.com/sites/site/documents/file.pdf, it opens fine in IE, using whatever IE uses to view PDFs.

It appears the click event in the library is causing a ruckus...


I've since removed the OWA server entirely from the farm (in dev) and now Adobe opens the file alone as expected. Adding it back in since it's def a OWA server issue.

Also tried installing the latest CU for OWA/OOS, but that errors out saying the expected version doesn't exist...

  • did SharePoint config wizard complete without any error? also try to clear the browser cache then try again.

  • The config wizard ran no problem. I just tried on a new browser, same issue. May 10, 2017 at 17:23
  • Have you solved the problem and how? Since we are experiencing the same issue after the SP2016 December 2019 CU update.

Install the May 2017 PU and try that. There was a bug, though I thought it was exclusive to 2013 with opening files where the path contained a space.

  • What/where indicates this should fix the problem? Hesitant to install updates "hoping" for a fix May 15, 2017 at 13:40
  • Windows Update installed support.microsoft.com/en-us/KB/3191880 over the weekend, I reran psconfig on each box. Still erroring May 15, 2017 at 14:47
