<message attachment>
CAUSE
This error may occur when the inbound SMTP mail message contains a reference to a character set that is not installed on the Microsoft Exchange Server. To verify this as the source of the problem, look for following field in the SMTP header of the message (there may be more than one):
Content-Type: <content type>; charset=<character set id>
Verify that the Microsoft Exchange Server computer has the proper code page installed for the character set referenced by charset.
RESOLUTION
To avoid receiving the content conversion error stated above, install the proper code page for the character set referenced in the mail message.
