Seeing as how Exchange 2010 Service Pack 3 won't be available until the first half of next year, and there is no status on if/when Exchange 2007 integration will be supported...how could you possibly update the links to Exchange 2013 at this time? We can't install Exchange 2013 in our organization even if we wanted to. I suspect only a handful of companies have moved to Exchange 2013 because of this requirement. Changing the links to Exchange 2013 makes little sense in this context.
How about if Microsoft changes the links back until at least Service Pack 3 is released. Would that be a good compromise here? When can we expect a solution?
