The Exchange Team Blog announced yesterday that the latest update for the Hybrid Configuration Wizard for Exchange now supports Exchange 2010 SP3. This will be a massive boost to many businesses who are currently on 2010 and moving to O365, and will make setting up the Hybrid configuration in 2010 much easier, taking away one of the few reasons to upgrade to Exchange 2013/2016.
