Microsoft Exchange Server has rapidly gained ground in a large number of companies. It is a versatile messaging and collaboration solution which works as a mail server and makes it possible to share calendars, book a meeting room, et cetera. Exchange can also function as a customer register. Both Exchange Server and its client Microsoft Outlook work on the Windows platform only.
Microsoft Outlook is a part of the Microsoft Office product family, enjoying corporate acceptance. Ximian Evolution is an excellent alternative to Outlook for Linux. However, Outlook and Evolution users need a server program to be able to collaborate.
Companies can currently choose OpenOffice and Evolution for their office needs. Unfortunately, lack of an open-source messaging and collaboration server often forces them to the Windows platform. There are no platform-independent solutions that could scale to more than 50 users as of yet.
The Prochange project is in need of talented Java and C++ developers to do research & development. The project consists of four individual parts: a main program, the Outlook plug-in, a virus and spam filter, and a WWW interface. Each subproject needs a few programmers. Companies and non-profit organizations are also encouraged to join!
