Is there a way I can disable the OWA feature for an CAS server? I don't want users to be able to use OWA on a certain server.

What else (i.e. other protocols) are you using the CAS for?

I totally agree with Mark. CAS is only designed for providing connection to non MAPI clients and EWS. If you want to disable web services on CAS you can stop the HTTP service but then the entire server has no meaning.MMilind Naphade | MCTS:M | http://www.msexchangegeek.com

I want to allow Active-Sync through this CAS server but not OWA. I have OWA on another CAS server protected by RSASecureID.

Hi,You can rename the OWA virtual directory in IISto work around this issue.ThanksAllen
