SYMPTOMS
Sending multiple attachments across the Internet Mail Connector (IMC) between two computers running Microsoft Exchange Server 4.0 may result in a message from the System Administrator saying "inbound mail failure - The message conversion failed." You may receive another message containing a Message.txt attachment.



CAUSE
The IMC does not validate line counts for binhex bodyparts in inbound non-MIME messages, due to a fix of an issue on decoding binhex data. For more information, see the following article in the Microsoft Knowledge Base:

164860 XFOR: Garbled Attachments Between Exchange 4.0 and 5.0 IMCs



WORKAROUND
To work around this problem, configure the IMCs to transfer messages in binhex, with TNEF disabled.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server 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):
