SharePoint 2013: Microsoft Word stopped working when opening from SharePoint document library


A user clicks on a Microsoft Word document in a document library in an externally facing SharePoint 2013 farm.  The user's local WinWord launches, and then a login dialog appears.  The user enters the usual authentication information, and then clicks OK.  The user is then prompted again to enter login information.  And so on.  If the user cancels out of the login prompt or clicks the "X", the users sees this error message:
Other users report similar experiences when trying to open other Microsoft Office documents in SharePoint 2013 document libraries.

This issue has been found to be associated with the installation of update KB3055034 for Microsoft Office 2010 that was released on October 13, 2015.


  • Uninstall KB3055034.
