When you write new messages in Outlook, you use the Message window. This window has a line for recipients (called the To line), a line for "carbon copied" recipients (the Cc line), a Subject line, and an area for the text of the message. Every new message must have at least one recipient. If you want, you can leave the Cc and Subject lines blank, but it’s a good idea to give your messages a subject.
In Outlook, click New on the Standard toolbar to display a new Message window.
Click the name of the address book you want to use, such as Contacts. The addresses in the selected address book appear in the box.
Click the name of the person to whom you want to send the new message.
Click To, Cc, or Bcc; Outlook copies the name to the specified message recipients list.
Repeat steps 5 and 6 until the message recipients list includes all the recipients you want to send the message to.
You can set up several different address books to store your e-mail recipients’ contact information. For example, you might have a company-wide address book that stores addresses and contact information for all internal employees. A second address book can be set up for external contacts, such as vendors, suppliers, and customers. A third address book could store personal contact information.
As you write your message, you do not have to press Enter at the end of each line. Keep typing and Outlook wraps the text to the next line. To create a new paragraph, press Enter. If you want each paragraph to be separated by two blank lines, press Enter twice at the end of each paragraph. This makes your messages easier to read than single-spaced messages.
You can apply special formatting to your message (see "Formatting E-Mail Messages"), but you might not want to. If you send mail to people who use a different e-mail program, they might not see the formatting that you intended. When in doubt, it’s usually a good policy to keep your messages simple so nothing gets lost in the translation.
