Went through the Exchange 2010 MS Course, reading the 70-662 Training Kit & watching the CBTNugget Exchange 2010 videos. So far I'm cruising having done a lot of labs and specifically worked on the Exchange 2003 to 2010 migration at my former employers. Figured I'd load up the brain and just go for the :EMA on the same day.

Federation Trusts....ech. I can understand why they're there but man I doubt if I'll ever actually be in a position to set one up. Oh and RBACs, can Microsoft get any more convoluted? It's really not all that complicated but boy is the Training Kit long-winded on this!
