XCON: Incoming Attachments Lost from Messages Sent over a Wang X.400 Connector (166586)
The information in this article applies to:
- Microsoft Exchange Server 4.0
- Microsoft Exchange Server 5.0 SP1
This article was previously published under Q166586 SYMPTOMS
When you send a message with attachments over a Wang X.400 Connector,
attachments are lost. You can open the mail message using any client, but
no attachments are present. Wang sends a Winmail.dat file with the
attachment. The Winmail.dat file and attachments are seen as bilaterally-
defined attributes in the P2 portion of an ASN.1 parsed message. An example
is shown below:
P2_Bilat_defined_prim [...attachment data here...]
P2_Bilat_defined_prim [...IPM.Microsoft Mail.Note....]
The first line includes the attachment information and the second line
contains the Winmail.dat attachment. The Winmail.dat attachment holds
properties of the attachment such as file name and it's exact position in
the message. These properties are described using Transport Neutral
Encapsulation Format, or TNEF.
CAUSE
The incoming Winmail.dat file from Wang does not include a display name
property, PR_DISPLAY_NAME, as part of the description for the attachment.
