An attached e-mail message is blank when you view the message in Outlook in an Exchange Server 2003 organization or in an Exchange 2000 Server organization

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 "message/rfc822."

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

�	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.

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