Microsoft Exchange Server 2007 Service Pack 1 (SP1) introduces many new features for each server role. This topic discusses the new and improved features that are added when you install Exchange 2007 SP1.

To download Exchange 2007 SP1, see Exchange Server 2007 Downloads.

New Deployment Options

You can install Exchange 2007 SP1 on a computer that is running the Windows Server 2008 operating system. For more information about the installation prerequisites for installing Exchange 2007 SP1 on a Windows Server 2008 computer, see How to Install Exchange 2007 SP1 and SP2 Prerequisites on Windows Server 2008 or Windows Vista. For more information about the supported operating systems for Exchange 2007 SP1, see Exchange 2007 System Requirements.

If Exchange 2007 SP1 is deployed on a computer that is running Windows Server 2008, you can enter IP addresses and IP address ranges in the Internet Protocol version 4 (IPv4) format, Internet Protocol version 6 (IPv6) format, or both formats. A default installation of Windows Server 2008 enables support for IPv4 and IPv6. If Exchange 2007 SP1 is deployed in this configuration, all server roles can send data to and receive data from devices, servers, and clients that use IPv6 addresses. For more information about Exchange 2007 SP1 support for IPv6 addresses, see IPv6 Support in Exchange 2007 SP1 and SP2.
