Microsoft Exchange Server 2007 contains several client-specific features that will improve the messaging experience for users and make it easier for administrators to manage their messaging environment. This topic provides a brief introduction to many of these features.
All non-MAPI messaging clients that access a mailbox in Exchange 2007 connect to an Exchange Server computer that has the Client Access server role installed. The Client Access server role can be installed on a computer that is running any of the other Exchange server roles except the Edge Transport server role. When clients access mailboxes on an Exchange server that has the Mailbox server role installed by using Office Outlook Web Access, Outlook Anywhere, Exchange ActiveSync, POP3, or IMAP4 clients, they connect to a Client Access server that communicates directly with the Mailbox server.
|The Client Access server role and the Mailbox server role can be installed on the same Exchange Server 2007 computer. In this case, the Client Access server role handles the client request and communicates with the Mailbox server role processes all on the same computer.|
Exchange 2007 provides several new features in Exchange ActiveSync. Some of these features are as follows:
- Support for HTML messages
- Support for follow-up flags
- Support for fast message retrieval
- Meeting attendee information
- Enhanced Exchange search
- Windows SharePoint Services and Windows file share
- Global address list search
- Password reset
- Expanded device password security policy settings
- Support for Out of Office configuration
- Self-service device management support through
Outlook Web Access
- Integrated device management support in the Exchange Management
- Support for allowing device synchronization by device ID
- Support for tasks synchronization
- Direct Push
|Many of these features are available only with the latest release of the Windows Mobile client software.|
|When you use Exchange ActiveSync and a mobile device to access Unified Messaging, you can download and listen to the attached .wma file for voice mail messages.|

Outlook Web Access
Outlook Web Access has several new and enhanced features in Exchange Server 2007. Some of those features include the following:
- New integrated search and advanced search capabilities.
- Improved message view. This includes grouping and sorting
features, message flags, and conversation view.
- Improved browsing and searching of Contacts and Address Book
- Enhanced calendar viewing. This includes meeting booking
improvements and color categories.
- Integrated reminders.
- Always up to date mail delivery.
- Advanced Out of Office scheduling and enhanced Out of Office
- Mobile device management.
- Improved experience for limited vision users.
Caution: When you use Pocket Internet Explorer to access Outlook Web Access Light, you may be able to listen to a voice mail message that is attached to an e-mail message. However, this functionality is not supported because Pocket Internet Explorer is not a supported platform for Outlook Web Access Light.

The Outlook Anywhere feature for Exchange 2007, formerly known as RPC over HTTP, provides access to your Exchange messaging environment for Microsoft Outlook 2003 or Outlook 2007 clients that connect to Exchange over the Internet. If you have installed the RPC over HTTP Proxy Windows networking component in Windows Server 2003 and enabled Outlook Anywhere on a computer that has the Client Access server role installed, users can use Outlook 2003 or Outlook 2007 to connect to their Exchange 2003 or Exchange 2007 mailbox by using Outlook Anywhere. By enabling Outlook Anywhere, Internet-based users have a reliable and efficient way to connect to their Exchange mailbox without having to create a virtual private network (VPN) connection to the corporate network.

Exchange 2007 enables you to use the Post Office Protocol version 3 (POP3) and Internet Message Access Protocol version 4 rev 1 (IMAP4) to support clients that still rely on these protocols. By default, both the POP3 service and the IMAP4 service are disabled for new installations of Exchange. Additionally, both protocols have limited access to calendar information for Exchange Server. The basic functionality of these two protocols is as follows:
- POP3 POP3 was designed to support
offline mail processing. With POP3, e-mail messages are removed
from the server, unless specified differently on the client, and
stored on the local POP3 client. This puts the data management and
security responsibility in the hands of the user.
- IMAP4 IMAP4 offers offline and online
access, but like POP3, IMAP4 does not offer advanced collaboration
features such as scheduling and group scheduling and task and
For more information about POP3 and IMAP4, see Managing POP3 and IMAP4.
Exchange 2007 includes a suite of new components that are designed to give users an enhanced calendar experience. The following components are included:
- Calendar Attendant
- Scheduling Attendant
- Resource Booking Attendant
- Availability Service
For more information about these calendar features, see Client Features in Outlook Web Access.
The Calendar Attendant processes meeting requests for all mailboxes. In earlier versions of Exchange, most of the meeting processing occurred on the client computer. The Calendar Attendant automatically puts new meetings on the calendar as tentative appointments, updates existing meetings with new information, and deletes out-of-date meeting requests without any client interaction.
The Scheduling Assistant simplifies booking meetings when clients are using Outlook Web Access or Outlook 2007. It automatically recommends the best days and times for meetings by providing a color-coded interface. It also lets users set their office hours.
For more information about scheduling, see Managing Resource Scheduling.
Resource Booking Attendant
Exchange 2007 identifies meeting resources as either a room or equipment and includes special attributes for each of these types of resources. For example, a room resource includes a capacity attribute. Custom attributes, such as audio-visual capabilities can also be defined. The Resource Booking attendant provides the following features:
- Limits who can book resources
- Enforces maximum meeting duration
- Schedules meetings only during working hours
- Forwards out-of-policy requests to delegates for approval
- Provides conflict information for declined meetings
For more information about resource scheduling, see Managing Resource Scheduling.
The Availability service is used to make free/busy information available for Outlook 2007 and Outlook Web Access clients. The Availability service provides free/busy information directly from the mailbox for users on Exchange 2007 and can be configured to retrieve free/busy information from public folders for users on earlier versions of Exchange Server. The Scheduling Assistant uses the Availability service to perform the following tasks:
- Retrieve current free/busy information for
Exchange 2007 mailboxes
- Retrieve current free/busy information from other
Exchange 2007 organizations
- Retrieve published free/busy information from public folders
for mailboxes on servers that have versions of Exchange that
are earlier than Exchange 2007
- View attendee working hours
- Show meeting time suggestions
For more information about the Availability service, see Managing the Availability Service.
Out of Office
Exchange 2007 includes several new and enhanced Out of Office features. These features include the following functionality:
- Users can schedule a future Out of Office time so that they do
not have to remember to set their status to Out of Office.
- Users can create two different Out of Office messages, one for
external users and one for users within their own organization.
- Users can decide to send their external Out of Office message
only to external recipients who are in their Contacts list.
- The Out of Office message is sent in HTML instead of plain
Administrators can manage the external Out of Office feature at the mailbox level. They can configure external Out of Office on a per-user and per-domain basis.
The Autodiscover service is a new feature in Exchange 2007 that automatically provides configuration information to Outlook and supported Exchange ActiveSync devices. In earlier versions of Microsoft Exchange, users were required to configure several settings to configure their profile. These settings included server name, mailbox name, and user account information. With the Autodiscover service in Exchange 2007, users need to provide only their e-mail address and password. The Autodiscover service returns an XML file that contains the user's configuration information. The Outlook 2007 client or supported Exchange ActiveSync device uses this information to create the user's profile. In addition to facilitating profile creation, the Autodiscover service also repairs any Exchange connection settings after a change has been made to the server settings or the user's profile.
Table 1 lists the client applications and protocols that support the use of the Autodiscover service.
