If I am on a network and setting up a new pc for an established user.....when he goes to log in to outlook, I have to reset up his outlook account under his user name or can it be done through the admin account some way without having the user being signed in under his own name?

If you have added a new computer to the network and have installed Ms-Outlook 2003 in it or if it is already installed in the computer,then you have to setup an account in MS-Outlook.

Is your network in workgroup or domain environment?
