Hi Ryan, As far as I understand using outlook to access exchange requires domain authentication. OWA can be set to use basic authentication (username/password dialog box) but I don't think this applies to outlook. You don't say whether the remote users are dialing in to your network or accessing it across the net. If across the net you will be required to open some ports (like RPC). While a Q article explains how to change these ports to other higher (unknown) ports I would not recommend doing this as a simple port scan could show them up, and security by obscurity has never worked for long. Instead look at a robust VPN solution if you want/need to do this. Note that RPC is fairly unworkable below about 40K/sec.

Do they have to be logged onto the domain somehow for it to connect ? They are basically laptop users running winxp prof in standalone mode which I am loath to bugger with. thanks
