The Outlook setup for the Faculty/Staff e-mail system is rather easy. All you need to do is fill out the account setup window as shown below using your own information. If you have not used Outlook on that computer anymore, you will receive a 'Welcome to Outlook' screen, just click 'Next' twice to get to the setup page. If you already have an account in Outlook and want to add this one, just click 'File' in the top left and then click 'Add Account'.
