AD Driver doesn't support mailbox moves Exchange 2010

I have all the latest patches for the
AD driver 3.5.14
DC Files - .DLL (dated 7/11/2011) - Fully patched for Exchange 2010
Driver config allows Add/Remove/Disable
When attempting to "Move" a mailbox by modifying homeMDB, trace 3 returns:

DirXML Log Event -------------------
Driver: \META\IDM\eDirMeta\mehealth domain
Channel: Subscriber
Object: \META\IDM\Person\Users\Ex-TESTBP
Status: Error
Message: Unsupported feature: Exchange mailbox move

I have verified through PS and the EMC that I have the proper rights

Any help would be much appreciated.
