Electronic mail for traditional text exchange as asynchronous communication means between computer users is widely built upon in many application areas. Whereas Multimedia-Mail systems - including text, graphics, still images, audio, video and documents - were limited to isolated communities - at least two very promising approaches are being under development: the MIME (Multipurpose Internet Mail Extension), an extension of Internet Mail as well as the Multimedia Teleservice based on CCITT Recommendation X.400(88) being under development within the BERKOM project funded by the German TELEKOM. The store-and-forward mechanism inherent to electronic mail is complemented in the later one by an additional exchange mechanism allowing the resolution of references to message content, e.g. video. Such references may be put into a message in place of the content itself. Internet/MIME and OSI/X.400, their interworking, asynchronous information server access via Multimedia-Mail, as well as possible future developments especially in the area of asynchronous Computer Supported Cooperative Work (CSCW) are discussed.
