Because internally OWA is using windows authentication, and your user is logged into the domain, hence his authentication token is being passed to the OWA server allowing him access to his mailbox. Now if he can access other illegally then there is a problem. But remotely from home OWA relies on basic authentication to prove the user has permission to access the mailbox, because this user is not on the domain.

My newly built Exchange 2000 box is running OWA. >From the inside network, when I go to the OWA page (outlook.mycompany.com) I get prompted for a username, password, and domain box. I have IE5 on NT4. >From the inside network, when my coworker goes to the OWA page (outlook.mycompany.com) he does not get prompted for a username, password, and domain box. It goes right into his mailbox without having to enter in credentials. He has IE5 with NT4. I had another user access the OWA page from home and they get prompted for the username, password, and domain. They used IE6. Anohter user accessed the OWA page from home, and they only got prompted for a username and password, NO domain. This person was not able to logon even though they supposedly used the domain\username appropriately. What's the deal with the 2 box logon versus the 3 box logon? And why do some PCs here need to authenticate and others go rihgt in? It's weird.
