New account problem

I am trying to add an account to outlook 2011 for mac and seem to be having some trouble. It's for my college email account, which uses MS exchange, so it should theoretically be easy to install. I click "add account", then enter the address username and domain as instructed on our website. This results in a prompt telling me it was redirected to a server (as expected), and it wants to know if I give it permission to automatically configure the settings. I click yes, and then it tells me that the authentication failed. The school's website doesn't have any instructions for manual configuration, and I've tried it multiple times and restarted so I know it isn't a one-time glitch. Does anybody have any ideas? Is there possibly a piece of software that I'm missing that allows it to interact with the server? Any help would be greatly appreciated. Thanks!
