Open-source challenge to Microsoft Exchange gains steam

By , Network World |  On-demand Software, cloud services, email

An open-source, cloud-based e-mail alternative to Microsoft Exchange called Open-Xchange has signed up two new service providers and predicts it will have 40 million users by the end of 2011.

Based in Germany, Open-Xchange has tripled its user base from 8 million to 24 million paid seats since 2008, with the help of three dozen service providers including 1&1 Internet, among the world's largest Web hosting companies. Open-Xchange has 7 million users in North America today, but says most of its 2011 growth will occur on this continent, in part due to new agreements with service providers Lunarpages of California and Cirrus Tech in Toronto.

COUNTERPOINT: Microsoft: 'We love open source'

"You will see a lot of new partners coming on board using Open-Xchange as their primary e-mail and collaboration solution," CEO Rafael Laguna said this week.

Microsoft Exchange Server, the 800-pound gorilla in the room, had a worldwide install base of 301 million mailboxes in 2010 and expects to reach 470 million by 2014, according to a market analysis by the Radicati Group. On-premises Exchange accounts for 76% of users, but that number will drop to 72% by 2014 because of growing demand for hosted, or "cloud" services.

Although Microsoft Exchange is still growing, Laguna predicts that third-party hosting companies will increasingly become wary of Microsoft because Redmond is offering e-mail and other hosted services through its own cloud platform, rather than relying solely on partner companies.

Open-Xchange's strategy is to make e-mail cheaper for both partners and customers. Open-Xchange mailbox prices vary by service provider, but will typically cost $5 per user per month, about the same as Microsoft's own Exchange Online.

But Laguna says the Open-Xchange price includes more than just basic e-mail, coming with mobile access through support for Exchange ActiveSync, social media features, collaboration and file management. In other words, you don't have to pay extra for SharePoint-like services.
