In a test environment right now with Exchange 2013. AD is just the basic installation, but I've added 2 organizational units. One named Iowa, the other named Kansas. In these organizational units (at the root of them) I have created a few users and added the users to Exchange. I can't figure out how to login to the OWA. I know this has to be really easy and I'm really dumb, but I'm stumped. Any help or references you can give me is MUCH appreciated.
