A request for information or services available on an intranet may be made by users on an extranet outside the intranet. An email is generated in an external server on the extranet in response to the request for information or services, and then sent from the external server to an internal server inside the intranet. The email comprises one or more approved forms based on the request, wherein specifics of the request are embedded into the body of the email. The email is processed at the internal server, in order to generate a response to the request, wherein the response is returned by the internal server to the external server in a reply email. The reply email includes an attachment containing the results of the processing performed by the internal server. The external server allows the user to access these results via an external graphical user interface.
