If you resend a Simple Mail Transfer Protocol (SMTP) mail by using Outlook (a Messaging Application Programming Interface [MAPI] client), the message ID in the SMTP mail that you resent may be the same as the message ID in the original SMTP mail.

NOTE: This behavior is different than the behavior in Exchange Server version 5.5. In Exchange Server 5.5, if you use Outlook to resend an SMTP mail, Exchange Server 5.5 uses a unique message ID for the resent message.
This problem occurs because the message ID is not modified when Outlook resends the original SMTP mail.
To resolve this problem, obtain the latest service pack for Microsoft Exchange 2000 Server. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:

Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server. This problem was first corrected in Microsoft Exchange 2000 Server Service Pack 1.
To confirm the message ID in Outlook:
  1. Open the SMTP mail that was sent from the Exchange 2000 server.
  2. On the View menu, click Options, and then click Internet Header.
  3. View the "Message-ID" line.
