Group-Office

Group-Office is a PHP based dual license commercial/open source groupware and CRM and DMS product developed by the Dutch company Intermesh. The open source version, Group-Office Community, is licensed under the AGPL, and is available via GitHub. GroupOffice Professional is a commercial product and offers additional business modules like project management, finance, HR and time tracking.

The online suite puts independent office applications onto a central server, making them accessible through a web browser. The suite includes file management, address book, calendar, email, notes, finance and project modules. The email client has IMAP and S/MIME support, the calendar supports iCalendar import, and it can be synchronised with personal digital assistants, mobile phones, and Microsoft Outlook. In the Professional version, it is possible to create templates to export to Open Document Format or Microsoft Word. Files can be managed in an inbuilt file manager, and accessed through WebDAV. Users may be managed within the application or in an LDAP system.

A LAMP environment is recommended on the server, and an OSNews.com review describes the installation process as "straightforward". Linux is recommended as the system software, but it also runs on other Unix systems, including BSD Unix, and Mac OS X. From version 2.17 and up, Microsoft Windows is also supported as the system software.

In March 2010 Group-Office was compared to other collaborative software in the German c't magazine. A special version was included for the bundled DVD.

As of November 2012, the project has had over 420,000 downloads from SourceForge since its public appearance in March 2003. SourceForge made a blog post about Group-Office in 2010.
