Exchange Server 2007 Mailbox Stamped as Legacy Mailbox

I ran in to this error during a migration when some mailboxes we’re created by a customer using Exchange 2003 management tools.  Approving Object User mailbox is already on the destination database

If you use the Exchange Server 2003/2000 extensions to Active Directory Users & Computers (ADUC) console to create mailboxes residing on Exchange Server 2007 servers, these mailboxes get stamped as legacy mailboxes.
