does Microsoft Live Mail support QuickBooks

I just upgraded computers - from Windows XP and Outlook mail to Windows 7 and Windows Live Mail for email. I use QuickBooks Pro 2012 and send billing statements via email. My problem is as follows: Outlook saved my emails sent from QuickBooks in a "sent mail" file. Windows Live does not save the emailed documents I send from QuickBooks. It does save emails I send from within the program. I called QuickBooks support. They said to contact you to find out if Windows Live Mail supports 3rd party software. If it does, QuickBooks tech support will work with me to fix the problem. The only program they are sure works is Outlook. If Windows Live Mail will not work with QuickBooks, I will buy Outlook.  Thank you for any help you can give me.
