Autodiscover A web service integrated with Exchange Server 2007 that facilitates
clients accessing their mailboxes. It is used to automatically set up accounts in
Outlook profiles. It is also used to determine which Client Access Server a remote
client should use based on where their mailbox server is located for optimal
performance.
• Availability Automatic load balancing of inbound and outbound connections
between Hub Transport Servers within an Active Directory site.
• Built on Active Directory The routing topology for Exchange Server 2007 servers
is based on the Active Directory site topology. It no longer requires the creation of
routing groups to control mail flow.
• Development A new set of web services to access mailbox content on Exchange
Mailbox Servers via HTML extends developers’ capabilities.
• Exchange Management Console Replacement tool for the Exchange System
Manager (ESM). The Exchange Management Console (EMC) is based on Microsoft
Management Console (MMC) 3.0 and combines all of the Exchange management
tasks into a single graphical interface. That means no more jumping between the
ESM and Active Directory Users and Computers (ADUC) to get Exchange
administrative tasks done.
• Exchange Management Shell A new command-line interface (CLI) from Microsoft
built on the PowerShell technology for advanced administrative tasks that cannot be
performed or automated in the Exchange Management Console.
• High availability for Mailbox servers Transaction Log Shipping is now available
for Mailbox Server roles in two flavors: Local Continuous Replication (LCR) and
Cluster Continuous Replication (CCR). Each creates a second copy of the production
database for rapid recovery scenarios. LCR stores the copy on the local server. CCR
stores the copy on another server. The Single Copy Cluster (SCC) is the latest
implementation for the traditional Exchange Microsoft Cluster Service.
• Message conversion The Hub Transport Server role has the ability to analyze the
formatting and encoding of messages and, based on the originator and recipient of
the message, make the necessary conversion to prevent formatting errors.
• Minimization of mail traffic Within an organization, least-hop routing is used to
determine the best path to a recipient’s mailbox. This has a greater potential of
reducing traffic than least-cost routing, which is subject to arbitrary administrative
constraints. Hub Transport Servers are responsible for determining the least-hop
route between Active Directory sites.
Performance improvements Exchange Server 2007 is a native 64-bit application.
Sixty-four-bit computing benefits are visible in the increased memory cache size,
increased number of storage groups, and increased number of information stores
per server.
• Recipient resolution It has always been possible to designate an expansion server
for a Distribution List. This is not as critical to do now that the Hub Transport
Servers are site-aware and will use the directory servers that are within the same
site for expanding distribution lists.
• Unified messaging For many years unified messaging has been available for
Exchange Server from third-party vendors. This technology, which integrates voice
messaging, faxing, and e-mail, has also been price-prohibitive for many small- and
medium-size businesses. By including unified messaging with Exchange Server
2007, all Exchange organizations can begin to take advantage of this powerful
productivity tool.
