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 >
<META http-equiv=Content-Type content="text/html; charset=unicode">
<META content="MSHTML 6.00.3790.2858" name=GENERATOR></HEAD>
<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 >
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.
