Understanding Exchange Role Based Access Control (RBAC)

Role Based Access Control (RBAC) is one of the most useful feature on Exchange 2016 or Exchange Online. Although RBAC has been there since Exchange 2007, It has been more enhanced and flexible on Exchange 2016. In Exchange 2007, the server permissions model applied only to the administrators who managed the Exchange 2007 infrastructure. In Exchange 2016, RBAC now controls both the administrative tasks that can be performed and the extent to which users can now administer their own mailbox and distribution groups.

RBAC assigns permission to users in to primary ways depending on whether the user is an administrator or specialist user, or an end-user.

  1. Management Role Groups.
  2. Management Role Assignment Policies.

Below are the details of the permission we have by default available on Exchange server.
