    Welcome to our forum.

    Client access server is an Exchange CAS server, which allow these MAPI connection. The RPC client access service is a service which provides data access through a single, common path of the Client Access server, with the exception of public folder requests, which are still made directly to the Mailbox server.

    I think you mean the RPC Client Access Service. This no longer exists in Exchange 2013 and beyond. It is all either RPC over HTTP or MAPI over HTTP now. Exchange 2010 was the last Exchange version to use RPC Client Access.

  • I don't know what you mean by "RPC Client Access Server".  Where did you learn of this term?
