Does the warning 6037 exist in the application log? If yes, please see the suggestion in this thread Please check if there’s any error information in the IIS log Please see if you can get expected error 600 in the xml page when browse /autodiscovery virtual directory [https://FQDNOfCas/Autodiscover/Autodiscover.xml] Please verify the setting of authentication of default virtual directories on the CAS serves (Reference) Please check if “Enable HTTP Keep-Alives” is checked properly in the IIS [6.0 | 7.0] Please run ExBPA against the CAS server for health checkJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com

Hi all, thanks for your response. The test worked immediately after posting this, it could have been i needed to give it sometime to initialize the changes to the RPC port since the address webmail.abs.local points to the VIP of the content switch.
