Hotfix available for Exchange 2007 disclaimer corruption

If you are running Exchange 2003 and 2007 in the same organization and you have enabled the disclaimer rule and create an e-mail on the Exchange 2003 server with OWA that gets routed by the Exchange 2007 server the e-mail might become corrupted.

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 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.
