In-Reply-To fields are lost when you move a mailbox in Exchange 2000 Server

When you use the Move Mailbox feature in Active Directory Users and Computers to move a mailbox, the In-Reply-To field is removed from the Simple Mail Transfer protocol (SMTP) header of any messages in the mailbox.

This problem occurs because the Move Mailbox operation does not retain the In-Reply-To field when the conversion from Internet format to MAPI format occurs.
