Dear all,Could you please share the knowledge for advantages and dis advantages on Exchange 2007sp2 if i update on runing exchange 2007 clustered sever on windows server2003 and also windows 2008.Thanks ,venkat.

No Diasadvantages as far as i know, like any other SP it will sure add some functrionalities. Some of them are: Enhanced Auditing: Certainly a beneficial feature for Exchange administrators looking to audit their Exchange servers. Dynamic Active Directory Schema Update and Validation: For those of you who have to deal with Active Directory schema updates, this is going to be a nice feature that prevents conflicts and helps to dynamically deploy future schema updates. Public Folder Quota Management: SP2 improves the PowerShell cmdlets needed to perform quota management. Centralized Organizational Settings: This is another PowerShell option to enable centralized management of Exchange organizational settings. Named Properties cmdlet: A new way to monitor named properties per database. New user Interface for Managing Diagnostic Logging: Found with the Exchange Management Console, this will allow for an easier logging experience for Exchange administrators to configure. Exchange Volume Snapshot Backup Functionality: There are some serious stipulations to the use of this add-in, which I will explain in a moment, but it is probably the most anticipated aspect of the service pack, even by administrators who will never use it.
