When a Microsoft Exchange 2007 server replicates a Contact object that is using a custom form, the custom message class is overwritten by the normal IPM.Contact class during content conversion. This issue occurs when a public store is replicated from Exchange 2007 server to any other public store that is hosted on an Exchange 2007 server or on an Exchange 2003 server. As a result, Exchange users cannot use the custom message class of the contact object in the public folders in an Exchange 2007 related environment.
To resolve this problem, install Update Rollup 6 for Exchange 2007 Service Pack 1. For more information about Update Rollup 6 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic:
