I managed to get my dad to make the switch at his office. The only problem is, he's the only Mac on a Windoze network. He needs to connect to the company's Exchange server, and he has Entourage 2004 to do so. They're running Exchange Server 2000. I can't figure out the Exchange Server address, and the other network guy won't help because it's a Mac! Can anyone tell me what the format for an Exchange Server address is? I should be able to figure it out from there. Thanks!
