By default, only people who have Exchange Organization Administrators permissions can manage both Exchange Server 2007 recipient and configuration data. However, to be able to create, modify, and delete objects within a specific domain, administrators who have Exchange Organization Administrator permissions also require membership in the Windows Account Operators security group or a higher-level security group.

In many organizations, there are separate administrators for Microsoft Exchange, the Active Directory directory service, and the telecommunications equipment. Therefore, administrative functions must be delegated to maintain distinct boundaries between different levels of administrative permissions. This is known as a split permissions model.
