Availability service Exchange 2007
Posted on 2011-02-16
We have 2 cas servers one internet facing one is internal.
autodiscover is working this question is more of trying to understand..
our internal domain is different than our external domain name.
so internal alias would be email@example.com
external would be firstname.lastname@example.org
From a computer added to the domain and connected to network if i run the test auto-configuration using my email address email@example.com it populates with the external urls correctly using the intenet facing cas server.
If i use my ad credentials firstname.lastname@example.org it pulls the services from the internal client access server not the internet facing cas server.
I do not understand how outlook/ exchange determines which CAS server to use internally or if there is a way to specify one over the other ?
Why doesnt it use the external facing cas server ?
the reason i ask is if we have a computer that is not a member of the domain but is on the network when a user with a valid account tryies to authenticate and open outlook they are getting a cert error to trust the cert. which is self signed cert of the internal cas server rather than hitting the internet facing cas server.
if the computer external and not connected to the domain trys to access outlook using autodiscover or outlook anywhere it works fine.
