You can set up Web Messaging to either confirm or not confirm that your message has been sent.

1. From the Main Menu page, click Preferences under Options, Personal.
2. On the Preferences page, locate "Confirm sent messages" and select Yes or No.
3. Click the Save button.

If you select Yes, then after you click the Send button, you'll see a "Send Mail Status" page; if the message is sent successfully, the words "message delivered" and "success" are displayed.
If you select No, then after you click the Send button, you will return to whatever page you were on when you clicked Compose.
