ADAC and Exchange 2003

We're running a 2003/2008 mixed domain at the moment, with Exchange 2003 mail server.

From our Windows 7 admin machines we use ADUC to administer users/mailboxes etc, but I've also been trying to use the Active Directory Administrative Center - which seems to work fine apart from the Exchange settings in Extensions. When you click any of the Exchange related tabs, ADAC simply crashes.

Has anyone used ADAC with Exchange 2003? Or is it only compatible with Exchange 2007 onwards?

Exchange 2003 isnt sulported on 2008 so I suspect you cant manage it using those tools.
