XCON: Message Body Truncated

The text of a message body is truncated when displayed by any Microsoft Exchange client. If the message is edited on the sending system to not include any null characters, the message can then be submitted to the Microsoft Exchange message transfer agent (MTA) and is displayed correctly.

The existence of null characters in the X.400 text body of the message seems to be in violation of X.400 standards. Null characters are not graphic characters and are not part of the ISO 646 graphic character set. The first X.400 text body part is handled as the PR_BODY, which is a null- terminate MAPI property. Any null characters contained in this body part are treated as terminators and the message body was truncated wherever the null characters occurred.

Microsoft has confirmed this to be a problem in Exchange version 4.0. This problem was corrected in the latest Microsoft Exchange 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
