Kolab is a Groupware Solution for Emails, Appointments, Contacts and more. It supports mixed client environments (Outlook/KDE) because of an open storage format. Any email client speaking standard protocols can be served.

For the full Kolab experience you need a Kolab Server and Kolab Clients. What makes the Kolab Concept outstanding is the focus on scalability, proven components and protocols. The implementations offered by us are Free Software (Open Source).

Kolab was created for the needs of the German Federal Office for Information Security (BSI) by contract in 2002-2004 and is used there in a heterogenous environment.

November 2005 Kolab won the Linux New Media Award: Category 'Best Groupware Server' [press release]. In September 2011 it received the CH Open Source "Community Award" 2011 [press release]
