What’s New in Exchange Server 2010

Microsoft Exchange Server 2010 brings a new and rich set of technologies, features, and services to the Exchange Server product line. This topic includes a list of the new features and functionality that are included in Exchange 2010. The list isn’t comprehensive, but it provides important information to use when you’re planning, deploying, and administering your Exchange 2010 organization. This topic also includes information about some of the limitations of this release and features from Exchange Server 2007 that have been removed.

New Rights-Protected E-Mail Functionality with Active Directory RMS

The following is a list of new rights-protected e-mail functionality with Active Directory Rights Management Services (AD RMS) that has been included in Exchange 2010:

•Transport rules to apply AD RMS protection to messages based on conditions.
•Persistent protection of attachments in rights-protected messages.
•Support for AD RMS templates.
•An Internet confidential AD RMS template for protection over the Internet.
•AD RMS protection for Unified Messaging voice mail messages
New Transport and Routing Functionality

The following is a list of new transport and routing functionality that has been included in Exchange 2010:

•Cross-premises mail routing An organization can choose to outsource some of their mailboxes to a hosted solution while maintaining their on-premises deployment. For example, a university can choose to host the mailboxes for all faculty and staff in their on-premises deployment and use a hosted solution for student mailboxes. Exchange 2010 allows routing of messages between the on-premises and hosted mailboxes.
•Enhanced disclaimers Exchange 2010 lets you add disclaimers that can include hyperlinks, images, and HTML-formatted text. You can also insert Active Directory attributes that are substituted for the sender’s attributes when a disclaimer rule is triggered.
•Transport rules integration with AD RMS Exchange 2010 gives you the ability to create rules that require AD RMS protection based on keywords or patterns.
•Moderated Transport Exchange 2010 provides an approval workflow for sending messages to recipients. When you configure a recipient for moderation, all messages sent to that recipient must go through an approval process.
•Shadow redundancy Messages that are submitted to an Exchange 2010 Hub Transport server are stored in the transport database until the next hop reports successful delivery of the message. If the next hop doesn’t report successful delivery and it fails, the message is resubmitted for delivery.
•Transport Dumpster truncation based on log copy status When messages that are in the dumpster are replicated to all mailbox databases, they’re removed from the dumpster.
•Latency SLA management Exchange 2010 Transport lets you measure service levels delivered relative to your service level agreement (SLA) goals. Exchange 2010 gives you the ability to measure latencies for each hop, as well as end-to-end latency.
•Transport database improvements Performance improvements in the Transport database result in reduced database I/O per second (IOPS) per message, which increases message throughput.
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:

•Local continuous replication (LCR)
•Single copy clusters (SCC)
In addition to these features, the concept of a clustered mailbox server no longer exists in Exchange 2010. Two other features, cluster continuous replication (CCR) and standby continuous replication (SCR), have been merged and renamed as a set of new features in Exchange 2010: incremental deployment, continuous mailbox availability, database mobility, database copies, and database availability groups.

For more information about Exchange 2010 high availability features, see New High Availability and Site Resilience Functionality.

New Messaging Policy and Compliance Features

Exchange 2010 compliance features make retention independent of users’ mailbox management and filing habits, and ensure retention policies are applied continuously. The following is a list of new messaging and compliance features that have been included in Exchange 2010:

•New interface for applying retention policies

•RBAC integration The Shell works with RBAC to give you and your users access only to the cmdlets and parameters they’re allowed to use. If your permissions don’t allow you to configure a certain feature, you aren’t given access to the cmdlets, parameters, or both, that manage that feature. For more information, see Understanding Role Based Access Control.
