I have an ISA server which is not in the domain, and rules were created for OWA works perfectly with the certificate, the drama is that the autodiscover as rpcproxy not work because the ISA blocks it. was tested for that opening all traffic that even so it blocks (An HTTP 403 Was Received Because ISA denied the URL Specified) reading and reading it appears that the ISA must be within the domain for this to work so is this true? Or is there any way to make standalone. Any other information would be really helpful.
