How-to: Delegate permissions to only create Exchange resource mailboxes using Active Roles Server
In order to create Exchange resource mailboxes, users must be granted the ability to create user accounts and manage Exchange resource mailboxes, which includes creation. This can be achieved by applying the following Active Roles Server Access Templates:
* Users - Create User Accounts
* Exchange - Manage Resource, Linked, and Shared Mailboxes
There are two built-in Active Roles Server templates that will provide the restricted ability to only create Resource Mailboxes in a targeted location.
In Active Roles Server, navigate to the OU that requires the delegation (i.e. Active Directory | mydomain.com | MyOU)
Have the delegated user confirm Exchange Resource Mailbox creation.
