As everyone else I too am having issues with OWA SSL,
I have looked at all hte articles I can find on this gone through various step by steps, from petri.il, mcseexchange.org, MS Kb and various others.
I have installed a Enterprise CA, the certificate was succesfully implemented into OWA,Configured SSL on the default web page and enabled form based auth, a first attempt brought up the SSL warning box and then went straight to Page cannot be displayed. I checked everything over and over again same thing, change back to normal works fine, recreated the OWA virtual dir in IIS and now even worse, no certificate warning come up it goes straight to Page cannot be displayed. Change back to normal and it works great. I am not going through a firewall and trying this locally.
Any ideas will be a great help.
I have already checked some of these pages
