Microsoft Portrait for Pocket PC and Handheld PC 1.4 was released on June 17. With Microsoft Portrait, users can either chat with Microsoft Portrait users or chat with MSN Messenger users in multiple sessions with multiple participants. Users who own Pocket PCs or Handheld PCs with operating systems earlier than Pocket PC 2002 can also enjoy .NET Messenger Service.

Microsoft Portrait is a research prototype for mobile video conferencing. It supports .NET Messenger Service and Internet Locator Service on PCs, Pocket PCs and Handheld PCs. It runs on local area networks, dialup networks and even wireless networks with bandwidths as low as 9.6 kilobits/second. Microsoft Portrait uses portrait-like video that always delivers the most important information in a video for a given bandwidth. In low bandwidths, portrait video possesses clearer shape, smoother motion, shorter latency and much cheaper computational cost than do conventional video technologies. Microsoft Portrait provides basic chat/voice/video functions almost anytime, anywhere, on any device.
