The server name and port have been set. I can use gmail to send forms. The problem is I can not create and send a customer an email from within Quickbooks using gmail When I try, I get the following error message "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 Moziliz Thunderbird. I can't imagine there are more Quickbooks customers using Mozilia Thunderbird than there are using gmail.
