no, then you won't have access to the internet.
Do you know what type of connection you are using in the office to get your email (pop3, imap, exchange)?
I'll be watching this thread and hoping for an answer.
I'm in the exact same situation as the original poster, and the guy I'm trying to help is using Exchange. He can connect with his MacBook to the Exchange Server using either Entourage or Mail, but Entourage tells him he can't connect to the Exchange Server when he connects (successfully) using VPN at his home.
I've read that you have to:
"Change the 'sending mail server' settings in your account settings to match your new ISPs mail server"
...but is there a way to do this automatically? This guy isn't a "techie," and to have to teach him how to go into Entourage--Tools--Accounts--Advanced and change server names each time he either plugs in to the work network or at home on his wi-fi would be painful, and sounds needless.
Or can a Mac, for some reason, NOT connect using Entourage 2004 to an Exchange Server over VPN?
