        Microsoft Releases Exchange 2007 SP3

		Microsoft this week released Exchange Server 2007 Service  Pack 3, which lets IT pros run the mail server on Windows Server 2008 R2.
The new service pack was released on Sunday, but was announced  yesterday, and can be downloaded here.  Microsoft took time to deliver this service pack because it entailed making a  lot of coding changes to Exchange 2007, the company explained  late last year. Microsoft promised back then that it would deliver SP3 in  the second half of this year, so this release came early.
The arrival of the service pack means that organizations  don't have to move off Exchange Server 2007 if they have migrated to Windows  Server 2008 R2 already. Exchange 2010 is currently available, having been  released as a final product in November, but some organizations  may not be ready to make that move. For example, Exchange 2010 uses a different  method of archiving and storing e-mails from its predecessors that may require  infrastructure changes.
However, the release  notes for SP3 suggest that IT pros won't have a simple upgrade process. SP3  will cause Active Directory schema changes, so Microsoft's release notes  suggest preparing Active Directory and domains prior to installing this service  pack.
SP3 is cumulative, meaning that it contains update rollups  through the fourth release. Consequently, it allows users to upgrade from  earlier service packs (such as SP1). However, Microsoft says that users must  first "uninstall all Interim Updates before you install  Exchange 2007 SP3." 
Removing SP3 appears to be less simple than installing it. The  only way to uninstall SP3 is to remove Exchange Server 2007 entirely and  reinstall an earlier version, according to Microsoft's release notes. 
SP3 will work on Windows Server 2008, but not if the OS was previously  upgraded. Microsoft offers just one approach: "To deploy  Exchange 2007 SP3 on an Windows Server 2008-based computer, you  must first install Windows Server 2008 on a computer that does not  have Exchange installed, and then install Exchange 2007 SP3."
Exchange Server 2007 SP3 supports both 32-bit and 64-bit  machines. However, a  Microsoft blog notes that "only the 64 bit is supported in Production  environment[s]."
A few new features are available with SP3. Highlights  include the ability to install Exchange Management Tools on Windows 7 computers,  as well as an improved search and password reset capabilities.
