Is there other ways you can protect your OWA for logins. We have some NT, Win 9X, and Win 2000 systems in our school. We have OWA so that teachers and staff can read their emails from home. When we configured the OWA security, it seemed that the only thing that worked was to use basic authentication. I am concerned about the amount of traffic that is transmitted in clear text. Does anyone have some suggestions to lock this down better but, keep functionality. Thank you, Scott Van Singel
