Ok ive found a program called OutTray.. which unfortuantly is a shareware which only last for 30days (Lame!).. but its only $10
"Outlook is the one program that needs to be open all the time. However, often there is no need for it in the task bar. OutTray sends Outlook and/or Outlook Express to the system tray when it has been minimized in the normal fashion. In this manner, Outlook can be kept running, while out of the way."
