Question
It has been reported that messages received from a Microsoft® Exchange user containing an attachment arrive as a winmail.dat file attachment in the Lotus Notes® client's mail file. These attachments are not able to be opened on the Notes client. Examination of the document properties reveals that the message was sent as a Content-Type: application/ms-tnef; name="winmail.dat".
Cause
This behavior is due to messages being sent from Exchange without MIME encoding turned on. Winmail.dat is attached to the message in uuencoded format. Information on how to prevent winmail data being sent to Internet users from MS Exchange is documented and publicly available from the Microsoft Support Web page, in the Microsoft Knowledge Base, article number Q138053:
http://support.microsoft.com/default.aspx?scid=KB;en-us;q138053

Answer
An enhancement request was submitted to Quality Engineering and functionality to decode winmail.dat attachments was added to Domino release 6.5.6, 7.0.2 and 8.0. Refer to the Upgrade Central site for details on upgrading Notes/Domino.
Excerpt from the Lotus Notes and Domino Release 6.5.6 MR fix list (available at http://www.ibm.com/developerworks/lotus):
Server
SPR# SBRN5PGPCN - This fix extracts attachments from TNEF streams. TNEF streams are sent from Microsoft Outlook users when the sender tells Outlook to send "rich text" to the recipient. The TNEF stream is a formerly proprietary Microsoft method for "tunneling" Microsoft Rich Text Format (RTF) data over the Internet. Microsoft has published the specification for the TNEF stream format. We now can decode TNEF streams (almost always sent as an attachment named 'winmail.dat') and extract any embedded file attachments. Any embedded file attachments are then attached to the message which is delivered to the Lotus Notes' recipients mail database.
To enable the fix a server notes.ini parameter must be used:
TNEFEnableConversion=1
NOTE: This parameter is associated with crashes in Domino 7.0.2 and 7.0.2 FP1. For more information, refer to the technote titled "SMTP task crashes on Domino when TNEFEnableConversion=1 is enabled" (# 1252932)
The fix also has some additional options:
-- This will keep the winmail.dat object as well as extract the regular attachments:
TNEFKeepAttachment=1
-- This will append a rich text entry containing the message body:
TNEFAttachRTF=1
Workarounds for earlier releases
The sender can configure their client to avoid TNEF Encoding. For details on how this is done, refer to this Microsoft document: |
