do you ahve a wifi connection available to connect o at home or another public wifi access?
menu.settings.wireless and networks, checkmark turn wifi on, open wifi connections and press on the connection you wish to connect to
outlook....it can be done, there are several references to it her in troubleshooting. I don't use it so I wouldn't know where to begin
