i have worked with exchange in past. On 2000 and 2003. Just a little bit of exposure in 2007. I wasn't sure if i should directly pursue for 2010 or take 2007 and do 2010 so i am confident and able to grasp entire concept.

any thoughts?

Thanks for your input.

I personally would recommend that you look at the technology that you will be using, so if your going to be working with 2007 then look at 2007, but for certificates your probably better off doing 2010 as its more up to date
