What's New in Exchange 2010

Applies to: Exchange Server 2010

Topic Last Modified: 2010-01-15

Microsoft Exchange Server 2010 brings a new and rich set of technologies, features, and services to the Exchange Server product line. New features and functionality in Exchange 2010 support several key concepts:

  • Flexible and reliable
  • Anywhere access
  • Protection and compliance

The following sections provide you with an overview of some of the important new features and functionality, which you can use when you're planning, deploying, and administering your Exchange 2010 organization.

(For information about features that have been discontinued or de-emphasized from Microsoft Exchange Server 2003 or Exchange Server 2007 to Exchange 2010, see Discontinued Features and De-Emphasized Functionality.)

The pressure to optimize your IT infrastructure to respond to changing business conditions demands agility and that means investing in solutions that provide you and your organization choice. Exchange 2010 gives you the flexibility to tailor your deployment based on your organization's unique needs and a simplified way to help keep e-mail continuously available for your users.

Exchange 2010 integrates high availability into the core architecture of Exchange to enable customers of all sizes and in all segments to economically deploy a messaging continuity service in their organization.

Exchange 2010 includes many changes to its core architecture. In Exchange 2010, new features such as incremental deployment, mailbox database copies, and database availability groups work with other features such as shadow redundancy and transport dumpster to provide a new, unified platform for high availability and site resilience.

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

The following is a list of core store functionality that's included or has been changed in Exchange 2010:

  • Deprecated storage groups
  • Mailbox databases no longer connected to the server object
  • Improvements in Extensible Storage Engine (ESE) for high availability, performance, and database mobility
  • Flattened Outlook store schema
  • Enhanced reporting with public folders

For more information about Exchange store and mailbox database features, see New Exchange Core Store Functionality.

In Exchange 2010, Role Based Access Control (RBAC) replaces the permissions model used in Exchange 2007. Using RBAC, you can define extremely broad or extremely precise permissions models based on the roles of your 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 role 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 features, see Understanding Permissions.

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

  • Shadow redundancy
  • MailTips
  • Moderated transport
  • Federated delivery
  • Latency service level agreement (SLA) management
  • End-to-end message tracking
  • Incremental EdgeSync
  • Transport rules integration with AD RMS
  • Transport dumpster improvements
  • Transport database improvements

For more information about transport features, see New Transport Functionality.

Exchange Server 2010 introduces the Exchange Server Deployment Assistant, or ExDeploy, a new Web-based tool that can help you with your Exchange deployment. ExDeploy asks you a few questions about your current environment and then generates a custom checklist and procedures that help simplify your deployment.

For more information, see Exchange 2010 Deployment Assistant.

The following is a list of the new core Exchange Management Console (EMC) features included in Exchange 2010. The core EMC refers to new functionality that affects how you use the EMC, and not how you use specific features:

  • Ability to add Exchange forests to the console tree
  • Customer Feedback start tab
  • Community and Resources
  • EMC command logging
  • Property dialog box command exposure
  • RBAC permissions aware for the EMC
  • Online Exchange Help

For more information about EMC features, see New Administrative Functionality in the Exchange Management Console.

The following is a list of features available in the new Exchange Management Shell:

  • Remote administration   With the new Shell, you can connect to remote servers running Exchange 2010 across the network with only Windows Management Framework installed, which includes Windows PowerShell. For more information, see Overview of Exchange Management Shell.
  • RBAC integration   The Shell works with RBAC to give you and your users access only to the cmdlets and parameters you and they are 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.
  • Administrator audit logging   Actions that result in the modification of Exchange organization configuration and other object properties in the EMC, the Web management interface, and the Shell can now be logged for later review. For more information, see Overview of Administrator Audit Logging.
  • Improved multiple-valued property syntax   Instead of running multiple commands to add and remove values from a single property, you can now add and remove values with a single command. For more information, see Modifying Multivalued Properties.

Administrators can use the Exchange Control Panel for Outlook Web App to manage some on-premises tasks. The following is a list of the administrative features available:

  • Text messaging integration
  • Voice messaging integration
  • Multiple mailbox search
  • Additional proxy addresses for mailboxes
  • Moderation and approval for distribution list submission

In addition, users have self-service capabilities in that they can perform administrative tasks via the Exchange Control Panel. The ECP enables users to perform common tasks without having to call the help desk. This allows your users to be more productive and allows IT staff to deliver more, while reducing support costs.

For more information, see Configure ECP Virtual Directory Properties.

The following is a list of the new mailbox and recipient functionality that's included or has been changed in Exchange 2010:

  • Ability for users to share information, such as calendar free/busy information and contacts with users who reside in a different organization
  • Improved scheduling and configuring for resource mailbox calendar processing
  • Ability to move a mailbox while the end user is still accessing it
  • Additional parameters added to distribution group cmdlets to allow users to create and manage their own distribution groups in Outlook Web App and Exchange 2010
  • Ability to appoint a moderator to regulate the flow of messages sent to a distribution group
  • Ability to manage folder-level permissions for all folders within a user's mailbox
  • Expanded bulk recipient management to allow you to bulk manage recipient properties
  • Ability to send mail to recipients from the EMC

For more information about mailbox and recipient features, see New Mailbox and Recipient Functionality.

The Microsoft Exchange Web Services (EWS) Managed API 1.0 provides a managed interface for developing client applications that use Exchange Web Services. Beginning with Exchange 2007 Service Pack 1 (SP1), the EWS Managed API simplifies the implementation of applications that communicate with Exchange. Built on the Exchange Web Services SOAP protocol and Autodiscover, the EWS Managed API provides a .NET interface to Exchange Web Services that's designed to be easy to learn, use, and maintain.

For more information, see Introducing the Exchange Web Services Managed API 1.0 and Microsoft Exchange Web Services Managed API 1.0.

Exchange 2010 uses client throttling policies to manage the performance of your Exchange organization. To do this, Exchange tracks the resources that each user consumes and enforces connection bandwidth limits as necessary.

Some of the benefits of client throttling include making sure that:

  • Users aren't intentionally or unintentionally taxing the system.
  • Users of various connectivity methods are proportionally sharing resources.

You manage client throttling policies with Shell cmdlets. For more information about client throttling policies, see Understanding Client Throttling Policies.

Enhancements in Exchange 2010 helps users get more done by helping them to access all of their communications—e-mail, voice mail, instant messaging—from virtually any platform, Web-browser, or device through industry standard protocols. Managing the flow of information into and out of an individual’s inbox daily can create overload and affect productivity and profitability. In response to this challenge, Exchange 2010 adds new productivity features that can help users more easily organize and effectively prioritize their communications.

The following is a list of new Unified Messaging features included in Exchange 2010:

  • Call answering rules

Exchange 2010 delivers new, integrated e-mail archiving and retention functionality, including granular multi-mailbox search and immediate legal hold. Exchange 2010 also helps you to better protect your company’s communications and e-mail through centrally managed information control capabilities. This includes the ability to more effectively intercept, moderate, encrypt, and block e-mail messages. Together, this functionality provides you with a flexible range of protection and control options, whether you want to automatically enforce controls or empower users to implement their own data protection.

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 included in Exchange 2010:
