Web mail Gibberish from 2003 to 2010 Exchange

I was migrating from Exchange 2003 to Exchange 2010. Email was configured to route through Exchange 2010 and out to the Internet if needed. If a user sent and email from the Web interface of Exchange 2003 to an outside internet recipient, the message looked like the following

䠼TML dir=ltr>䠼EAD>㰊META content="text/html; charset=unicode" http-equiv=Content-Type>㰊META name=GENERATOR content="MSHTML 8.00.6001.19328"㰾/HEAD>㰊BODY> 䐼IV㰾FONT color=#000000 size=2 face=Arial>OWA 2003 Gibberish Test㱴/FONT>⼼DIV>⼼BODY㰾/HTML>

 

Note the red was the actual message. If the same thing was sent to a recipient on Exchange 2010 the message appeared just fine.

 

The issue happened once a disclaimer was set up as a transport rule. So the disclaimer was causing the issue. Disable the transport rule, the issue goes away. Enable the rule, it comes back.

 

Cause:

This problem occurs because Outlook Web Access for Exchange 2003 sets an e-mail message to an incorrect character set. When the message is routed by the Exchange 2007 or 2010 server that has the Disclaimer rule enabled, the e-mail message is converted to incorrect HTML tagging based on the incorrect character set. Then, the message is corrupted by the incorrect tagging.

 

The fix?

A patch just for this issue. Once the patch was applied to all of the Exchange 2003 servers, all was well.
