Maybe some of your users reported that they receive messages from  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


For further information, you can also refer to Microsoft Knowledge Base article number Q196784:

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. The new functionality allows the server to convert the winmail.dat automatically. To enable the feature the following notes.ini parameters must be added to your Lotus Notes Domino Servers:

TNEFEnableConversion=1

 

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

-- This will set the log level (if needed): TNEFConverter_Log_Level=10

-- This will break a S/Mime signature (couldn´t break a S/Mime encryption) to extract the content: TNEFBreakSMIME=1

 

Sample implementation:

TNEFEnableConversion=1

TNEFAttachRTF=1

TNEFConverter_Log_Level=20

TNEFKeepAttachment=0

TNEFBreakSMIME=1

 

 

Related Information:

Attachments to messages received from the Internet are named as winmail.dat

 


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)
