Configure Airlock Gateway for Outlook Anywhere

Microsoft introduced Outlook Anywhere with Exchange 2003 (formerly known as RPC over HTTP). It enables Outlook clients to access their Exchange mailbox without the need for a VPN connection. This is achieved by encapsulating the RPC request in HTTP requests.

The following contents show the steps required to configure Outlook Anywhere behind Airlock Gateway.

Chapter-related warnings

With Exchange 2013 SP1, Microsoft created a successor called MAPI over HTTP, which comes with improved Outlook connectivity and responsiveness.

  • The Airlock Gateway mapping template contains the configuration for RPC over HTTP and MAPI over HTTP. Nevertheless, MAPI over HTTP has many advantages and should be the preferred method for Outlook connectivity.

Chapter-related prerequisites

  • The previously described configuration steps have been carried out.
  • You must be logged in as an admin in the Airlock Gateway Configuration Center.
