Today, Exchange Server 2010 Service Pack 2 is ready to download. As announced last May, SP2 incorporates customer feedback to bring users new features, as well as requested fixes and rollups released prior to SP2. Just like SP1, there is no separate download for client and server languages. Users will only need to download and install separate language packs if they have Unified Messaging.
