Share button function to open email and attach

[VO@BHB]

I got a new computer and I forget how to change the setting of my Email/Share button in Adobe Pro DC.  I used to click the email button and it would automatically open my default email application (Outlook) and attach the PDF.  I didn't have to go through all the other chosing options for sharing each time.  I remember I had to do something special to get this functionality, it wasn't just a standard default I could choose in the preferences.  (Though I do wish this was an option).  Does anyone know how to do this? 

Thanks in advance!
