Outlook Settings

I'd like to configure it manually but the program won't allow me.  Whenever I try to get to account settings it tells me that an account with that email address has already been set up.  What I'm trying to do is delete this account and set it up properly manually.  There must be a way to get to the outlook account settings.  If I can get there perhaps I can just change the settings so it points to my existing email set up.  Or, as I said, I'd like to delete the existing account and set it up manually.
