SYMPTOMS

Consider the following scenario:
  • You have a mixed Microsoft Exchange Server 2003 and Microsoft Exchange Server 2007 or Exchange Server 2010 mail environment.
  • The Disclaimer rule is enabled on the Exchange 2007 or Exchange 2010 server.
  • An e-mail message that is generated from Microsoft Office Outlook Web Access on Exchange 2003 is routed by using an Exchange 2007 or Exchange 2010 Server.
In this scenario, the e-mail message is corrupted. When this problem occurs, the e-mail message is shown as the following HTML format.

< h t m l > < h e a d > < m e t a h t t p - e q u i v = " C o n t e n t - T y p e " c o n t e n t = " t e x t / h t m l ; c h a r s e t = u t f - 1 6 " > < / h e a d > < b o d y > <HTML dir=ltr><HEAD> <META http-equiv=Content-Type content="text/html; charset=unicode"> <META content="MSHTML 6.00.3790.2858" name=GENERATOR></HEAD> <BODY> <DIV><FONT face=Arial color=#000000 size=2>aaaa</FONT></DIV></BODY></HTML< b r > < h r > < f o n t f a c e = " A r i a l " c o l o r = " G r a y " s i z e = " & # 4 3 ; 0 " > M y D i s c l a i m e r < b r > < / f o n t > < / b o d y > < / h t m l >

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.
