NUREMBERG, Germany, September 21, 2009 – Open-Xchange, the leading provider of open source groupware, will be hosting its first Open-Xchange Partner Summit on October 8 at the RheinEnergie Stadion in Cologne, Germany, providing the partner community with a unique forum to learn how to advance their business with e-mail and collaboration services.

Open-Xchange offers open source collaboration services as both an on-premise solution and Software-as-a-Service (SaaS) using exactly the same source code -- enabling SaaS providers and on-premise channel partners to join forces and leverage their respective strengths. System integrators and resellers can partner with service providers to offer hosted Open-Xchange to their customer base without any upfront investments to set up a complex and secure hosting infrastructure. SaaS providers can benefit from resellers' and system integrators' local and regional customer base and in-depth technical and consulting expertise.

The Open-Xchange Summit features separate tracks for system integrators, SaaS providers and ISVs. Keynotes and tracks provide in-depth technology and marketing strategy sessions for business and technical professionals interested in learning more about how to grow their business with Open-Xchange messaging and collaboration solutions. The Open-Xchange Partner Summit concludes with an evening networking event. For the detailed agenda and free registration, visit www.open-xchange.com/en/partnersummit.
