I have two Exchange 2007 in Exchange organization. All roles (except Edge and UM role) are on one server (one physical server for each Exchange server). One Exchange server is production with valid SSL certificate and one is test with self-sign certificate. Occasionally Outlook 2007 goes to test Exchange server to use EWS and then users get certification warning about certification trust (because test Exchange have self-sign certificate).

How Outlook 2007/2010 choose which Exchange Web Service to use and is it possible to control that?

Sincerely,

Tomislav

For internal domain joined computers, Outlook will connect to an AD SCP to gather autodiscover connection points. Every time you add a CAS server into the environment, the CAS gets added to the list. When Outlook connects it will choose one at random. The SCP will return the value of the AutodiscoverInternalURI defined by the Set-ClientAccessServer command. You should update the non-production server's AutodiscoverInternalURI paramenter to match an FQDN that is in your certificate and that points to the valid server. Usually: Set-ClientAccessServer -Identity CASServer -AutoDiscoverServiceInternalUri https://autodiscover.domain.com/autodiscover/autodiscover.xml

Your Outlook clients will then use the returned Autodiscover URL to gather all of the URLs that Outlook needs to communicate for OOF, Availability, etc. These are defined by configuring your CAS serices URLs. For Example Set-WebServicesVirtualDirectory, Set-OABVirtualDirectory, etc.
