Exchange Server 2010 Service Pack 3 (SP3) has been released, raising the Exchange version number to 18.104.22.168.
For those still unaware, the 550 MB file contains the full set of binaries; you can use it to upgrade existing installations or deploy new Exchange 2010 SP3 installations.
Besides the usual set of fixes, SP3 introduces the following features:
· Exchange 2013 Coexistence
This Service Pack for Exchange 2010 adds coexistence with Exchange 2013. However, it requires Exchange Server 2013 Cumulative Update 1 (CU1), which hasn’t been released yet.
· Windows Server 2012 Support
This Service Pack enables you to deploy Exchange Server 2010 on Windows Server 2012 platform.
· Internet Explorer 10
You can now use Internet Explorer 10 to connect to Exchange 2010.
· Sent Items Management
You can now control behavior of Send-As or Send-on-Behalf messages regarding the folder used to store a copy of the sent message. This mimics Delegated Send Items options available in Outlook.
Be advised that after installing SP3 on Mailbox servers, the databases are upgraded to the SP3 version database schema. An SP3 database can’t be mounted on pre-SP3 Mailbox servers. Keep this in mind when upgrading your DAG (you will temporarily have limited fallback or switchover options) or for example when relying on database portability for some reason. Note that upgrading databases can be time consuming, especially with RTM or low SP version databases as the database will be upgrade from RTM to SP1, SP1 to SP2 and finally SP2 to SP3.
After preparing your forest for Exchange 2010 SP3, the schema version number will have changed.
