Exchange 2010 Service Pack 3 is now available

The eagerly awaited Service Pack 3 for Exchange 2010 is now available.

Its main new feature is of course support for coexistence with Exchange 2013 so an upgrade scenario is now finally supported. Well… almost, as you need to wait for Cumulative Update 1 (CU1) for Exchange 2013 which is due this quarter as well.

Once that is available, you are free to keep versions mixed as well in case you only want to add or replace Exchange servers when needed. You can now also install Exchange 2010 on Windows Server 2012

A cool new end-user feature is control over in which folder “Sent As” and “On Behalf Of” messages should be stored; the mailbox owner or the mail sender. You can control this via OWA. PowerShell support for this was already added to Exchange 2010 SP2 RU4.
