EDIT:  This feature is now live in the Exchange 2010 SP2 RU3 build of Exchange.   Will add a post about this change at a future date.


This post is to clarify that a previously discussed feature that was intended for Exchange 2010 SP1 is not in the SP1 final build. 


The feature I am referring to is the allow/block cross site RPC Client Access connections.  This sometimes comes up in workshops and discussions with clients regarding CAS & DAG interaction.  There are numerous blogs (http://tinyurl.com/4yysfp5) and a couple of books that describe the feature. 

If you read the current TechNet documentation on the Set-DatabaseAvailabilitygroup cmdlet then you will see that the feature is listed as reserved.  This is available here:
