Microsoft Exchange Server 2007 Service Pack 3 (SP3) has been designed specifically to meet the challenges facing our customers and to help address the needs of all the different businesses and organizations utilizing our Exchange Server 2007 enterprise messaging system.

Exchange Server 2007 SP3 is a mission-critical communications tool that enables employees to be more productive and access their information anywhere and anytime while providing a messaging system that enables rich, efficient access to e-mail, calendar items, voice mail, and contacts.

For administrators, Exchange Server 2007 SP3 provides further flexibility with the addition of Windows Server 2008 R2 support for server roles and Windows 7 support for the Exchange management tools. These additions, along with enhancements for the advanced protection options against e-mail security threats, such as spam and viruses and the tools which help manage internal compliance and high availability needs provide Exchange administrators with the tools they need to manage their Exchange 2007 environments efficiently.

Clean installations of Exchange 2007 SP3 on a new server are possible by using this download in the same manner as you would install Exchange 2007 RTM, Exchange 2007 SP1 or Exchange 2007 SP2.
