default mail client

Please improve Endnote to allow applications other than Mail (e.g. Microsoft outlook) to be the default mail client. Currently I am unable to email references/pdfs to students because it states Mail must be my default may client. Many users (including me) must use Micosoft Outlook as the default mail client at their work. I’ve never encountered another application that requires Mail be used as the default mail client. 

Thank you,

Michael Rosen
