Released to business customers as part of Microsoft's roll-out wave of new products. It includes new clustering options, x64 support for greater scalability, voice mail integration, better search and support for Web services, better filtering options, and a new Outlook Web Access interface. Exchange 2007 also dropped support for Exchange 5.5 migrations, routing groups, admin groups, Outlook Mobile Access, X.400, and some API interfaces, amongst other features.
Exchange Server 2007 (v8, code name E12, or with SP1 v8.1) runs only on x64 versions of Windows Server. This requirement applies to supported production environments only; a 32-bit trial version is available for download and testing. Hence, companies currently running Exchange Server on 32-bit hardware will be required to replace or migrate hardware if they wish to upgrade to the new version. Companies that are currently running Exchange Server on 64-bit capable hardware are still required to migrate from their existing Exchange 2000/2003 servers to a new 2007 server since in-place upgrades are not supported in 2007.
The first beta of Exchange Server 2007 (then named "Exchange 12" or E12) was released in December 2005 to a very limited number of beta testers. A wider beta was made available via TechNet Plus and MSDN subscriptions in March 2006 according to the Microsoft Exchange team blog. On April 25, 2006, Microsoft announced that the next version of Exchange Server would be called "Exchange Server 2007".

Exchange Management Shell
a new command-line shell and scripting language for system administration (based on Windows PowerShell). Shell users can perform every task that can be performed in the Exchange Server graphical user interface plus additional tasks, and can program often-used or complex tasks into scripts that can be saved, shared, and re-used. The Exchange Management Shell has over 375 unique commands to manage features of Microsoft Exchange Server 2007.
Lets users receive voice mail, e-mail, and faxes in their mailboxes, and lets them access their mailboxes from cell phones and other wireless devices. Voice commands can be given to control and listen to e-mail over the phone (and also send some basic messages, like "I'll be late")
Increased database maximum size limit
Database size is now limited to 16TB per database
Increased maximum storage groups and mail databases per server
5 each for Standard Edition (from 1 each in Exchange Server 2003 Standard), and to 50 each for Enterprise Edition (from 4 groups and 20 databases in Exchange Server 2003 Enterprise).
Configure Outlook Anywhere
Formerly known as RPC over HTTP provides external access to Microsoft Exchange Server 2007 for users. If you want Microsoft Office Outlook 2007 user profiles to be automatically configured to connect to Exchange 2007, configure the Autodiscover service. This also provides external URLs for Exchange services such as the Availability service and offline address book.

This is extended to 50 databases in up to 50 storage groups. Supports LCR (Local Continuous Replication), SCR (Standby Continuous Replication), SCC (Single Copy Clustering), and CCR (Clustered Continuous Replication).
