New Permissions Functionality
In Exchange 2010, Role Based Access Control (RBAC) has replaced the permissions model that was used in Exchange 2007. RBAC lets you define extremely broad or extremely precise permissions models based on the roles of you administrators and users.
For administrators and specialist users, management role groups define what these users can manage in the organization. Role groups associate role group members to a set of management roles that define what the members can do. By adding or removing users as members of role groups, and adding or removing role assignments to or from a role group, you can control what aspects of the organization the members can manage.
For end users, management role assignment policies define what users can configure on their own mailbox. Assignment policies are applied to every mailbox either by default or manually, and enable you to control whether users can change their personal information, contact information, distribution group membership, and so on.
Both group groups and role assignment policies are assigned management roles. Management roles control access to the cmdlets and parameters required to perform a task. For example, if a cmdlet exists on a management role, and that role is assigned to a role group, the members of that role group can then use that cmdlet.
For more information about RBAC, see Overview of Permissions.
New High Availability Functionality
Exchange 2010 integrates high availability into the core architecture of Microsoft Exchange to enable customers of all sizes and in all segments to be able to economically deploy a messaging continuity service in their organization.
Exchange 2010 includes many changes to its core architecture. The following features in Exchange 2007 and Exchange 2007 Service Pack 1 (SP1) no longer exist in Exchange 2010:
