SYMPTOMS
A message created by Collaboration Data Objects (CDO) with an attachment but no body, may be rejected as undeliverable by a foreign X.400 system. If a similar message is created by using Microsoft Outlook 2000, it is successfully accepted by the foreign system.



CAUSE
When you use CDO to create a message that contains an attachment, but no body, the PR_BODY field appears to be null. When this is converted to X.400 format, a P2_IA5Text body part is created with a hexadecimal value of 16 00. The &quot;00&quot; may cause the receiving foreign X.400 system to assume that the message is malformed, and reject it.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in Exchange Server 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 4.
