Delegate Role Assignments

Applies to: Exchange Server 2010

Management role delegation enables role assignees to assign a specified management role to other management role groups, management role assignment policies, users, or universal security groups (USG). By default, only members of the Organization Management management role group can delegate role assignments. When a new installation of Microsoft Exchange Server 2010 is deployed, only the user account that installed Exchange 2010 is a member of the Organization Management role group.

If you assign a delegating role assignment to a role group, any member of the role group can delegate the associated management role to other role assignees.


Delegating role assignments doesn't give the role assignee the permissions granted by the role, only the ability to assign the role to others. If you want to also give the permissions granted by the role to the role assignee, you must also create a regular role assignment. To create a regular role assignment, see the following topics:
Add a Role to a Role Group
Add a Role to an Assignment Policy
Add a Role to a User or USG


This topic discusses management role assignment delegation. If you want to delegate who can add members to or remove members from role groups, which is the recommended method of delegation, see Add or Remove a Role Group Delegate.

You can create delegating role assignments using the same predefined scopes, recipient filter or server-filter-based scopes, server list-based scopes, and organizational unit (OU) scopes that can be used to create regular or exclusive scopes. The only difference between creating a regular role assignment and a delegating role assignment is the addition of the Delegating switch to the command.
