The problem is not that I can't sign into Gmail from Quickbooks. Sending forms like invoices and statements works fine. The problem arises when I try to use a customers email address as shown in their account in Quickbooks. As soon as I select an email address in a customers account I get a "WARNING" that says "YOUR EMAIL CANNOT BE SENT BECAUSE QUICKBOOKS DOES NOT SUPPORT THE EMAIL PROGRAM YOU ARE USING. THE SUPPORTED PROGRAMS ARE OUTLOOK, OUTLOOK EXPRESS, WINDOWS MAIL AND MOZILIA THUNDERBIRD".
