I have a macro that creates emails. It uses Outlook ala.
Code:
    Set OutApp = CreateObject("Outlook.Application")
    OutApp.Session.Logon
But this Excel app will now also be used on desktops that use Windows Live Mail rather than Outlook.

I've hunted but... Anyone know the Object name for the Live Mail client? And is there a way for me to find out which one is installed?
