Hi Though outlook has been around for quite some time but not a big change has been made to it. I could see only 2 major upgrades to the previous Microsoft outlook versions. First one being, outlook now allows more effective office communication by integrating their communications server with outlook a lot better. Also, this time around grouping has been allowed that would definitely help me in keeping track of inbox & sent item threads. Rest, it is old outlook with new name at least to me in first look.
