You probably know that after you add recipient addresses, compose your message, format the text, spell check the message, and insert a signature in the e-mail, you are ready to send the message. But you can use a couple of ways to actually send the message on its way.
The fastest way to send the message using the mouse is to click the Send button on the Message toolbar. If you prefer, press Ctrl+Enter. In either case, your message is heading out to its destination. If you are working offline, the message is placed in the Outbox until you connect to the Internet and send and receive your messages.
