I'm a teacher, and the tech people at my school set up my school e-mail through Entourage. This is awesome when I'm at school, but for some reason Entourage can only "connect to Exchange" when I'm at school, which means I have to go through the school website (and a thousand other steps) to check my e-mail at home. How can I fix this so that I can receive and send e-mail through Entourage from home?
