If you are unsure of the person's address and you know that their address is stored in your address book, you can send a message directly from the Address Book, by doing the following:
Select the person(s) e-mail address(es) you want to send an e-mail message to from the Address book list.
Click the Send To or Copy To button in the Address Book and the selected address will appear in the Write mail Send to or Copy to box.
Type the message subject heading and content and then click the Send Now if you are currently connected to M-Web or click the Send Later button if you want to send the message out at a later stage.
Note
You can use a semi colon (;) to separate one e-mail address from another in the Send to text box.
