Consider the following scenario:
This problem occurs because Transport Service handles the server-side rules in Exchange Server 2007. Transport Service resolves a contact's address and then encodes the display name of the contact. If there is a charset in the MIME message, the character set is used for encoding the display name. In this scenario, Exchange Server 2007 does not recognize that there are non-ASCII characters involved. Therefore, US-ASCII characters are used for encoding, and the non-ASCII characters in the display name are displayed as "?" characters.
To resolve this problem, install the following update rollup:
