Can someone help me with the following question? Licensing questions make me want to pull my hair out. What does Exchange 2007 no longer have that was included in the license of Exchange 2003?

the most notable thing seems to be outlook is no longer included. read the 2nd chart at the bottom of the page: http://www.microsoft.com/exchange/evaluation/editions.mspx also: http://www.tmcnet.com/news/2006/07/31/1755020.htm
