Zarafa
Zarafa's open source groupware combines the usability of Outlook with the stability and flexibility of a Linux server. Not only is Outlook supported natively, but users can also use WebAccess, which has the same look and feel as Web 2.0 Outlook, all ActiveSync-compatible mobile devices and BlackBerry handhelds via the BlackBerry Enterprise Serve.
