So, what’s new in SP2? Exchange Server 2007 SP2 introduces many new features for each server role.
Migration, transition and co-existence with Exchange Server 2010 – Only after installing Exchange Server 2007 SP2 you will be able deploy Exchange Server 2010 in your organization. First, you must upgrade all of the Client Access servers. Next, any Exchange 2007 Server, regardless of server role, in the Active Directory site you are transitioning, must be upgraded to Exchange 2007 SP2.
Exchange Backup Functionality built-in to Windows Server 2008 – Exchange Server 2007 RTM and SP1 didn’t have this capability on Windows Server 2008 and additional solutions were required to perform this task. Finally, Exchange 2007 Service Pack 2 includes a VSS plug-in for Windows Server Backup to support Exchange backups. Now you can use Windows Server Backup in Windows Server 2008 to back up and restore Exchange 2007 SP2 databases. The new plug-in, called WSBExchange.exe, is automatically installed by SP2 on all Exchange 2007 Mailbox servers. The plug-in enables Windows Server Backup to be able to make Exchange-aware VSS backups.
Enhanced Auditing – New Exchange auditing events and audit log repository enable Exchange administrators to more easily audit the activities occurring on their Exchange servers. This simplifies the auditing process itself, and makes review of audited events easier by segregating audited events in a dedicated location.
Dynamic Active Directory Schema Update and Validation – The dynamic AD schema update and validation feature allows for future schema updates to be dynamic deployed as well as proactively preventing conflicts whenever a new property is added to the AD schema. Once this capability is deployed it will enable easier management of future schema updates and will prevent support issues when adding properties that don’t exist in the AD schema. SP2 now supports the following: The addition of attributes that are independent of schema changes; The ability to reference attributes that may not exist in the schema; Compatibility with Microsoft Exchange Server 2010 code and more.
Public Folder Quota Management – SP2 enables a consistent way to manage quotas by improving the current PowerShell cmdlets to perform quota management tasks.
Centralized Organizational Settings – SP2 introduces new PowerShell option that enable centralized management of many of the Exchange organization settings.
Named Properties cmdlets – SP2 enables Exchange administrators to monitor their named property usage per database.
