Older versions of Exchange server (5.5 and earlier) used its own method for access control using permissions that were stored in the Exchange directory store. Through the use of ACL’s permissions can be applied granularly allowing, or denying, access to specific objects. With this approach, permissions flow from top to bottom and allow for fine tuning of permissions on all objects. Server Level – The lowest level is the server level and restricts administrative control to the specified server.An administrative group can be compared to an Active Directory domain, where the domain is the administrative boundary. Administrative Group Level – This level includes all Exchange servers in the Administrative group. This is the top level and users with administrative permissions at this level can manage the entire Exchange organization. Organization Level – Includes all Exchange Administrative Groups and the Exchange servers they contain.Exchange uses both the Windows access control model, made up of Access Control Lists (ACL) and a hierarchal permission structure.Įxchange provides three levels at which you can apply Access Control Lists (ACL’s) and administrative permissions. In order to manage and protect the data in the Exchange server a number of different administrative permissions are required.
