  • Outlook Anywhere not working (Mutual Authentication)

    Hey guys and gals

    Hoping someone can point me in the right direction here. Im trying to Outlook anywhere working for a customer, through an Isa2006 server, natting to a CAS server in the internal network.

    When i run the test at "", it fails on the following line:

    Testing SSL mutual authentication with RPC Proxy server

    Failed to verify Mutual Authentication

    The page also provides a link to this MS Page

    Now I've tried to read up on this but im more confused than when I first started. The customer has a wildcard SSL cert installed on the ISA & CAS server, everything works normally internally through Autodiscover, but i just cant get Outlook Anywhere working externally.

    Any help would be appreciated.
