Microsoft releases SP1 for Exchange Server 2007

Microsoft released the first service pack for Exchange Server 2007 on Thursday, fixing software bugs and adding some new features to make the product more stable and useful for business customers. However, Microsoft’s Exchange partners said there are still improvements that could be made so the latest version of Exchange can provide customers with a more complete end-to-end messaging architecture.

Users can download Exchange Server 2007 Service Pack 1 (SP1) from Microsoft’s Web site. Anticipating the long-awaited release of Windows Server 2008 early next year, Microsoft added support for that product into SP1, as well as features that allow for integration between Exchange Server 2007 and Office Communications Server 2007.

Windows Server 2008 support in particular is important for customers, because there is clustering technology in Windows Server 2008 that replaces existing technology in Windows Server 2000 and 2003 that has become obsolete, said Keith McCall, chief technology officer and founder of Azaleos in Seattle. Azaleos offers an Exchange hardware appliance and other e-mail management and archiving services.

Windows Server 2008 support in SP1 provides Exchange customers with “a more effective high-availability solution for managing infrastructure,” he said.

For the companies offering Exchange Server as a hosted service, SP1 has technology to resolve problems the product had with multitenancy, said Rurik Bradbury, vice-president of strategy for Microsoft hosting partner Intermedia. Multitenancy is when a single Exchange Server environment serves multiple customers. Improvements to multitenancy in SP1 make the product more stable for hosting partners, said Bradbury, whose company has been testing the service pack.

Microsoft also did an about-face and reinstalled the “public folders” feature of Outlook Web Access, the Web-based version of the Outlook e-mail client, in SP1, he said. Workgroups within an organization traditionally could share information through public folders on Outlook Web Access. However, Microsoft “was trying to make everyone move” to its Office SharePoint Server to provide this feature, “but now backtracked in the face of an outcry from Exchange customers,” Bradbury said.

In addition to these improvements, Microsoft also added a new disaster-recovery feature to Exchange called Standby Continuous Replication (SCR), the company said. SCR allows administrators to put a server running Exchange in a separate geographic location to provide failover. But Bradbury was critical of the new feature, saying that providing this kind of failover is “difficult and would still involve e-mail downtime,” as well as increase the cost of Exchange Server because it requires deploying an extra server for the product.

One feature that Azaleos’ McCall said is still missing from Exchange is message archiving for storage management and compliance purposes. He said Microsoft partners have been requesting this addition to the product for a while, but Microsoft has made other features such as business continuity and high availability its primary goals for Exchange until now. Azaleos offers its own archiving service for Exchange, McCall said.
