Microsoft has announced that it is to provide a means of delivering messaging and presence-enabled applications to enterprise workers on the move, and that it has linked up with RIM (Research in Motion) to integrate Office Live Communications Server 2005 with the BlackBerry services that RIM provides. A new Windows Mobile client, based on the same user interface found in Office Communicator 2005, will provide e-mail, phone, instant messaging, SMS and other communications technologies such as videoconferencing and Web conferencing, and will do so by means of an array of digital hardware and wired or wireless networks.
