SYMPTOMS
The Microsoft Exchange Internet Mail Connector (IMC) might lose mail under specific conditions. No events or error messages will be reported if the conditions that cause the IMC to lose mail arise. The only symptom of this problem is the failure to receive a mail message without the originator ever receiving a Non-Delivery Report (NDR).



MORE INFORMATION
There are two possible conditions that can cause the IMC to lose mail. When the IMC is receiving inbound messages and has successfully begun creating a message, the IMC will make a call to OpenStreamOnFile for the incoming message. If the call to OpenStreamOnFile fails, the IMC will fail to create the message and will delete the inbound message without logging any errors.

The IMC can also lose messages when processing outbound messages. When attempting to send a message outbound, the IMC will attempt to open the message residing in the store. If the IMC is unable to open the message, the IMC will delete the message from the store. No notification of this problem will occur.



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 Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
