How it works OpenHand is a client/server remote access software solution based on Microsoft's .NET Framework. The client connects to the OpenHand server over a TCP/IP connection. The OpenHand server then connects to the Microsoft® Exchange server or Lotus Domino® server to retrieve users' personal information (email, calendar, contacts and tasks) which is then made available to the client device.
The server application behaves as if it were just an ordinary Outlook or Notes client application so no configuration modifications need to be made to mission critical PIM servers. Software need not be installed on these servers either, ensuring that the installation of OpenHand has no impact on the availability of email for users.
