Managing and modifying access control lists is easy with role based access control (RBAC) feature in Hosted Exchange Server 2010. In fact, the process of managing the control lists is not required with RBAC. In Exchange Server 2007, access control lists created several challenges, such as modifying ACLs without causing unintended consequences, maintaining ACL modifications through upgrades, and troubleshooting problems that occurred due to using ACLs in a nonstandard way. But with RBAC in Hosted Exchange 2010, things have become much smoother.

RBAC allows you to control both what administrators and end-users can do. This feature of Microsoft Exchange Server 2010 enables solutions providers to easily and flexibly control what administrators and users can access. It allows certain tasks to be accomplished, while the role scope determines which resources can be administered. On the other hand, in Exchange 2007, the server permissions model are available only to the administrators who manage Exchange 2007. In Exchange 2010 Hosting, RBAC controls both the administrative tasks that can be performed and the extent to which users can now administer their own mailbox and distribution groups.

Phew! Life would be so much with this new feature of Microsoft Exchange Server! Isn’t it? So switch over to Hosted Exchange 2010 soon and enjoy!
