SYMPTOMS
In a Microsoft Exchange Server 2003 organization or in a Microsoft Exchange 2000 Server organization, you receive an e-mail message that has an attached e-mail message in Microsoft Outlook. When you view the attached message, the message is blank. This problem occurs when all the following conditions are true:
 * An event sink is registered on the Exchange store in the Exchange Server organization. Additionally, the event sink is active.

Note An event sink may be registered by third-party antivirus software services.
 * Outlook is configured as a MAPI client.
 * A rule that automatically forwards the received message is configured in Outlook.
 * The content type of the attached message is &quot;message/rfc822.&quot;

Similarly, the recipient of the automatically forwarded message receives a blank attachment.



WORKAROUND

 * Do not use an event sink on the Exchange store.
 * Do not use a rule that automatically forwards messages in Outlook.
 * Use a non-MAPI client to receive and forward messages.
