SYMPTOMS
When sending a message from a Microsoft Exchange Server system to an ISOCOR message transfer agent (MTA), the ISOCOR system's client, when opening the message, may encounter the following error:
After closing the error message, the contents of the message will appear. However, the attachment will be missing.
CAUSE
The problem occurs because the ISOCOR system does not support the use of Body Part 15 (BP15)-type attachments.
RESOLUTION
To solve this problem, go into the Exchange Server Administrator program and open the properties page for the X.400 connection to the ISOCOR system. Go to the Advanced tab and in the X.400 Link Options section, click to clear the "Allow BP15" checkbox. Restart the MTA service and send the message again. This behavior is by product design.
