Am I right that OWA CAS-to-CAS proxying was always possible only if SP and RU levels are exactly the same on the proxying CAS and on the CAS to which it is proxying? And if yes, then what is the meaning of this article?  Maybe this SP2 RU1 feature will break proxying for ActiveSync (which works when SP and RU levels are different as opposed to OWA proxying)?
