XCON: ISOCOR Message Transfer Agent Does Not Accept Body Part 15 Attachments (169998)



The information in this article applies to:

  • Microsoft Exchange Server 4.0
  • Microsoft Exchange Server 5.0
  • Microsoft Exchange Server 5.5

This article was previously published under Q169998

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:
Error decoding folder INTRAY; invalid length
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.
