I gave up on this yesterday after Rachelle in tech support told me that the problem was the most recent release of my software (I moved from R6 to R8 apparently) was at issue.  R8 no longer supports the outlook button but here is a clue for me.  I was having trouble getting Acrobat DC to send a file by email in outlook.  It was also not recognizing my default mail.  The tech got on, repaired Office 2013 and acrobat DC.  We rebooted and suddently the button that "was removed from this release" is there.  Not loving tech support at QB right now.  12 hours of work on this.
