When you send an e-mail message in Microsoft Office Outlook 2003, the From field in the e-mail message that is in your Sent Items folder may not contain any e-mail addresses. Also, you may receive a non-delivery report (NDR) message in your Inbox folder that is similar to the following:

This issue occurs if all the following are true:

•	You are using Microsoft Office Outlook 2003 Service Pack 1 (SP1).
•	You are using either a Post Office Protocol version 3 (POP3) account or an Internet Message Access Protocol (IMAP) account.
•	The e-mail message was sent to one or more people who are not in your domain.
•	Outlook 2003 is configured to receive an NDR message for all recipients.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

Currently, there is no resolution for this issue. Because the e-mail message was not delivered to any recipients, the fact that you have an empty From field in an-email message that is in your Sent Items folder would be known only by you.
