Why do I recieve a "authorization failed. retry?" error message when using Netscape for OWA on Exchange 5.5 with SP3. I change the Authentication method from basic authentication to Windows NT Challenge response on IIS 4.0 under directory security.

Out of the box Netscape doesn't work with NTLM authentication. However I've seen a "plugin" before now on Netscape's site that allows it to work.

A better bet if you want to be secure is to use basic authentication, but put SSL on your web server running OWA.

Thanks
