I'm using SharePoint 2010 and MS Office 2013 up until recently I was having no issues with this combination. Starting over the last week all MS Office documents will not open. The MS Office application will do 1 of 3 things:

  1. Run the launch window with "opening wfeserver/library/document.docx" until the user kills the program

  2. Open the program and go to a Not Responding state until the user kills the program

  3. Prompt the user with:

    sorry, we cannot open wfeserver/library/document.docx server isn't responding

So far, the only solution I found was to restart the IIS server on the WFE. I'm looking for what is causing this issue. is there a service or application pool that deals directly with MS Office files? Any ideas?

Note: Central Admin is running off another server. Central Admin doesn't experience the same issue only the sites on the WFE server. Also, this only affects MS Office files.


start task manager, and end-task called MSOSYNC.EXE

    This was something affecting all users at the same time not just a handful at different times. What I did to resolve the issue was set a IIS to refresh its connections every 2 hours. – Woodsy Feb 1 '16 at 20:44
