The following two steps describe how to enable Office 2013 and Office 2010 applications to open Office file types directly from a server that supports only Basic authentication over a non-SSL connection. You should follow these steps only if you are confident that the connection between the user and the web server is secure. A direct cable connection or a dedicated line would be considered optimal for secure connections. 

Note For Office 2013 and Office 2010 applications, both steps are required. For other Office applications, only step 1 is required.
