Exchange 2007 journal reports and winmail.dat attachments
I worked an issue today that I thought I would mention since there seems to be others out there with it.
Issue:
Journal Reports that were forwarded to an external smtp address were received with winmail.dat attachment.
Cause for this issue:
Exchange 2007 Journal Message Behavior for encoding:
- Messages sent to an internal journal recipient are TNEF encoded.
- Messages which are sent to an external SMTP address are still encoded like Exchange Server 2003 did them.
Exchange 2003 Journal Message Behavior for encoding:
- Only the attachments for the journal messages are TNEF encoded.
The content type is defined as multipart/mixed.
The message body is Content-Type: text/plain;
The attachment is encoded as Content-Type: application/ms-tnef; name="winmail.dat".
*By having Outlook forward the journal report to the external recipient, the message was then treated as any other external message instead of as a journal report.
Resolution:
1. Create a distribution list to journal to.
2. Add the journal mailbox as a member to that group.
3. Add a mail enabled contact (for the external recipient) as a member of the group.
4. Go to the properties of the database that you want to journal & add the distribution group as the journal recipient.
There have been quite a few changes in message journaling in Exchange 2007, you will want to read up on it. Here is a link to the whitepaper. http://technet.microsoft.com/en-us/library/bb738122.aspx
