Open-Xchange is a software company that develops, markets and sells web-based communication, collaboration and office productivity software, which enables full integration of email, documents, scheduling and social media. The company is privately owned and headquartered in Cologne, Germany, with offices in Finland, Netherlands, Japan and United States (2018 information).
Founded in 2005 by Rafael Laguna and Frank Hoberg, the company started with development of a Linux-based email and groupware solution that was positioned as open-source alternative to Microsoft Exchange.
In 2013, Open-Xchange released OX App Suite, a web desktop application, as well as OX Documents, a cloud-based office productivity suite. The software was also made available for on-premises installations.
OX App Suite includes a set of applications that are meant for email, contacts, calendars, media and documents. It integrates Google Mail, Hotmail, Facebook, Twitter and LinkedIn, and can be used as an alternative to Microsoft Exchange Server and Office 365.
Open-Xchange introduced OX Documents, a browser-based office productivity suite compatible with Microsoft Office and OpenDocument files.
In February 2014, the company added OX Drive to the OX App Suite family, which provides file syncing and collaboration features both in-browser and with native applications available for Android, iOS, Windows 7/8 and OS X devices.
In September 2014, the company introduced a tool called OX Guard to their existing open source email server. Individuals and businesses can use the software to operate their own email services. In July 2015 the company announced PGP support for OX Guard.
The company partners with Dutch software vendor Summa to create OX Messenger, a WebRTC based solution for secure peer to peer chat, voice and video communications that is integrated into OX App Suite.
Open-Xchange is being offered in 5 different versions, two hosting solutions (OX Server Edition and OX Hosting Edition) and three software packages (OX App Suite, OX Web Edition, OX Community Edition). Out of these 5 versions only OX Community Edition can be used permanently without paid subscription.
OX App Suite can be downloaded for evaluation and non-supported use. Updates, maintenance, technical support and access to components with 3rd party licenses such as Connector for Microsoft Outlook and Connector for Business Mobility (ActiveSync) need a separate subscription plan.
OX Community Edition Backend is released under the GNU General Public License, version 2, the Frontend is released under Creative Commons Share Alike, Non Commercial, Attribution. These licenses allow use without payment, including in commercial environments. The restriction to Non Commercial in the Creative Commons license for the Frontend restricts re-distribution to third parties, i.e. hosted deployments for third parties. However, since the front-end license prohibits commercial re-distribution, the software is neither free software nor open source software since the definitions of both require such re-distribution to be permitted.
