Earlier versions of Microsoft Exchange server had only two levels of permission delegation: organization groups and administrative groups. In many Exchange environments, administrative groups were the only way to make sure that a specific server administrator had the necessary permissions to manage a specific Exchange server or group of servers but did not have permissions to manage other Exchange servers in the organization.

In the earlier versions of Exchange, the Exchange administrator created administrative groups and then added the required Exchange servers to the administrative group. This approach didn't give the Exchange administrator enough flexibility when delegating administrative tasks at the server level. In Exchange Server 2007, the administrative group has been delegated. This approach gives the Exchange administrator more precise control and flexibility when controlling administrative access at the server level.

Unified Messaging Server Management

Exchange 2007 Unified Messaging (UM) servers can be managed by delegating the appropriate users or groups to the Exchange Server Administrator role to manage UM servers in the organization. For more information about UM server management, see How to Delegate Server Administration.
