Open-Xchange: Disrupting Hosted Microsoft Exchange?

Open-Xchange: Disrupting Hosted Microsoft Exchange?Open-Xchange, which makes open source groupware, is quietly gaining momentum with European managed service providers and solutions providers that are moving into the hosting market.

I am not suggesting the hosted Microsoft Exchange empire will collapse in Europe (or elsewhere). But MSPs seeking to differentiate in the market now have numerous open source options from which to choose -- including Open-Xchange. Here's a quick look at the four MSPs that have taken the Open-Xchange plunge.

According to an Open-Xchange press release, recent adopters include:

  •  Swiss Dynamic-NET (, which allegedly ranks among the top 10 ISPs in Switzerland. The company has 20,000 customers and 500 resellers.
  • VAPS (, which serves 2,000 VW and Audi car dealers in Germany. VAPS claims to have 30,000 accounts served by the centralized e-mail system.
  • Econtec, a system integrator in Germany, uses Open-Xchange Hosting Edition to offer e-mail, contacts and calendar functionality to a health care provider with more than 750 offices in Germany and Austria.
  • SIEGNETZ (, also of Germany, recent launched hosted Open-Xchange with its own brand, OJONET ( .
The move to hosted Open-Xchange is occurring across the world. Other adopters, according to Open-Xchange, include Network Solutions (U.S.), 1&1 Internet (Germany), JMF (Japan), OVH (France) and Hostpoint (Switzerland).
