Exchnage 2013 OWA and ECP not working when you login using the webmail.FQDN you get username and password and then you get a http 500 error.
But if you do it from the server on 127.0.0.1/oqa it works fine. I have checcked bindings and followed every article I can find, and removed local host bindings for 80 and 443 bur nothing seems to work, any one got any suggestions Thanks -- Good news everyone, you have just received an e-mail from me!
