Undeliverable message when you send Internet mail in Outlook

When you send Internet mail by using Microsoft Outlook, you may receive an undeliverable message in your Inbox from the system administrator.

This behavior occurs because of a busy or unreachable Internet Mail server when you connect through your Internet service provider (ISP).

When you use the Internet E-Mail Service that is provided with Outlook, the original message item is removed from the Outbox and placed in the Sent Items folder.

To resolve this behavior, verify the availability of your Internet Mail server and resend the message. To do this:

1. Open the Undeliverable message in your Inbox.
2. On the Tools menu, click Send Again.
3. When the original message appears, click Send on the Tools menu.

To successfully send an Internet message, the Internet Mail server must be available. Your ISP can supply the name of the server or its IP Address.
