Well, I've taken some time off from studying as my job demands have been high. But now I'm back and ready to take this sucker down.
I just finished setting up my lab of two separate forests each with their own independent Exchange organization on VMWare Workstation. Each forest also has one Virtual PC with Office 2010 running on it and I have verified email going between the organizations.
My first two attempts were met with Fails because I don't know all the nuance differences between 2007 & 2010 as well as the different Power Shell syntax's. My hope this time around is to really lab the Heck out of Exchange and get very comfortable with EMS. I have a heavy focus on Message Compliance & Monitoring this time around as those are the areas I scored low in on my first two attempts.
I'll post back as I have my "Ah Ha" moments and when I schedule/take the exam.
