I am using MS Exchange 2007. My application is sending multipart messages containing both plain text and html versions. One Transport rule is configured to add disclaimer text to all emails. The issue is that Exchange server discards my original plain text part and regenerate plain text part from html version (after adding disclaimer text). There is no issue if this transport rule is disabled. Is there any way to instruct Exchange to add disclaimer text individually to each part instead of first adding in html part and then regenerate plain text part from html version?

Hi I dont think you can do that from hub transport rule. Because in hub transport rule, the Action is to apply an HTML disclaimer to the message. For the disclaimer text, Exchange 2010 inserts disclaimers into e-mail messages by using the same message format as the original message. So if you would like to apply an HTML disclaimer, it will regenerate plain text part to html version. For more information, you can have a view on below link Understanding Disclaimers http://technet.microsoft.com/en-us/library/bb124352.aspx Transport Rule Actions http://technet.microsoft.com/en-us/library/aa998315.aspx Hope that helps CheersZi Feng TechNet Community Support

Hi Feng, Thanks for your response. I am using Exchange 2007 and my disclaimer is plain text. My email is multipart having plain text and html part. The problem is that Exchange server discards my original plain text part and replace it with text-version-of-html part+disclaimer. My original message is part 1 - This is plain text part 2 - This is HTML What user is receiving from Exchange is part 1 - This is HTML Disclaimer text part 2 - This is HTML Disclaimer text My original "This is plain text" is gone. Hope this will clarify my problem better.

Hi Did you mean by when a user received the message, he got two Disclaimer text, and Part1 plain text had been replaced by Part2 HTML? CheersZi Feng TechNet Community Support

Yes. And Part 1 is plain text version of html part.
