Composing an e‑mail message is just like writing a note in a word processor. Once you've finished composing your message, you type your recipients' e‑mail addresses and the subject of your message in the appropriate boxes, and your message is ready to send.
Keep in mind that you need to create an e‑mail account for yourself in Windows Mail to be able to send e‑mail messages.
Open Windows Mail by clicking the Start button , clicking All Programs, and then clicking Windows Mail.
Click the File menu, point to New, and then click Mail Message to open a new message composition window.
In the To: box, type the e‑mail address for each of your primary recipients. In the Cc: box, type the e‑mail address for each of the secondary recipients to whom you want to send a copy of the mail. If you're sending to multiple addresses, separate them with semicolons.
In the Subject: box, type the subject of your message.
Click in the main message window and type your message.
Once you're satisfied with your message, do one of the following:
To send the message right away, click the Send button.
To send the message at a later time, click the File menu, and then click Send Later.
The message will be sent the next time you click the Send/Receive button.
If you're writing a lengthy message and want to come back to finish it later, you can save it at any time. To save a message, click the File menu, and then click Save. Saved and unsent messages are stored in the Drafts folder.
