Ximian EvolutionXimian Evolution is a personal information manager and workgroup information management tool for Linux and UNIX. It combines e-mail, calendar, address book, and task list management. Its user interface and functionality imitates much of Outlook. It does have some distinguishing features, such as full-text indexing of all incoming mail and a resulting "vFolders" (virtual folders) feature, saved searches that behave like regular mail folders. Ximian Evolution is part of Gnome office.
Ximian Evolution can optionally connect to an Microsoft Exchange 2000 server using its web interface and an Evolution add-on called "Connector".
