Where is Sent Items Management? This feature was put into Exchange 2010 SP3 formally, but forgotten in Exchange 2010 RTM CU1? How did that one get past QA? Imagine telling your customer that yes, you have this great feature in SP3 and once we install SP3 you will be able to upgrade to 2013. However, if you go to Exchange 2013, you will lose this same great feature.
While I understand that Sent Items Management is not a game changer or a show stopper of a feature, it still makes the point that CU1 still seems rushed even with the late release date.
I would also like to add that according to the EAC, when I add a new database I need to restart the Information Store service on the server.
