I'm trying to setup a hosting environment where each customer has his own OWA forms-based login page. The basics already work - Segregated users cannot see each other in the addressbooks, public folders etc etc.I tried the following approach:1. Create a new folder2. Createa new subfolder (named after the hosted group)3. Create a new site in IIS manager4.Named the site after the hosted group, set the physical path to the subfolder, application pool to use the DefaultAppPool, binding to use HTTPS, 2ndIP address,certificate to use the default Exchange certificate5. Ran the following command in a shell: New-OwaVirtualDirectory -owaversion:exchange2007 -websitename "NamedInStep4"So far so good. A site is created, a new OWA instance is copied to said site, but what I cannot get working is the login method. Whenever I logon, I get ye olde challenge-response window while instead, I want the forms-based login.StepsI tried so far:Set the new site to Forms-based authentication with UPN in Exchange Management ConsoleCopied the exisiting OWA site's Authentication/SSL settings over to the new site via IIS manager (Root site: Anonymous authentication, Require (128-bit) SSL / OWA application: Basic Authentication, Require (128-bit) SSL)Set the new site's Authentication to Forms Authentication via IIS managerNothing worked so far or managed to make it worse. Any advice on what I am possibly doing wrong, or is what I want to accomplish just not possible?Thanks in advance

Yes, but I'm not sure as to whether it is the answer. You are saying that I have to look into getting the Autodiscover stuff working first?
