SQL 2012 filetable fileshare, cannot open Outlook msg file

I have mapped a filetable fileshare to a local drive.  I am able to open most file types except an Outlook msg file.  I get the standard "Cannot open file T:\etc..etc.msg.  The file may not exist, you may not have permission to open it, ...." 

The only other (unanswered) post I could find is http://stackoverflow.com/questions/11950779/sql-server-2012-filetable-not-able-to-open-outlook-2010-email-message.

Is this an issue or am I doing something wrong?

Thanks
