SOGo, formerly Scalable OpenGroupware.org, is an open source collaborative software (groupware) server with a focus on simplicity and scalability.
SOGo provides collaboration for Mozilla Thunderbird, Microsoft Outlook, Apple Calendar, and BlackBerry client users. Its features include the ability to share calendars, address books, and email using an open source, cross-platform environment. The Funambol middleware and the Funambol SOGo Connector allow SyncML clients to synchronize contacts, events, and tasks.
SOGo supports standard groupware capabilities including CalDAV, CalDAV auto-scheduling, CardDAV, WebDAV Sync, WebDAV ACLs, and iCalendar.
Microsoft Outlook support is provided through an OpenChange storage provider to remove the MAPI dependency for sharing address books, calendars, and emails. Native connectivity to Microsoft Outlook allows SOGo to emulate a Microsoft Exchange server to Outlook clients.
Mobile devices are generally handled through the Microsoft Exchange ActiveSync (EAS) protocol. Devices such Apple's iPhone are handled natively by SOGo as iOS supports CalDAV and CardDAV. Other devices can access the web interface, which is responsive since release 3.0.0.
History
The project's history began in 1996 with LSOffice, an online collaboration platform developed by German Internet service provider MDlink. LSOffice was renamed SKYRiX Groupware Server, and Skyrix Software AG of Magdeburg, Germany, was spun off to take over the product in 2000. It was based upon the SOPE application server, an open source derivative of WebObjects developed by the same company.
Around 2003, much of the SKYRiX Groupware Server source code was released as an open source project called OpenGroupware.org ("OGo"). Though it was intended to compliment the OpenOffice.org office productivity suite, the two projects were independent.
In early 2004, a large client contracted with Skyrix Software to deploy OpenGroupware.org to 60,000 users. The result of this project was Scalable OpenGroupware.org ("SOGo"), a fork of OpenGroupware.org focused on scalability.
SOGo remains actively maintained. Open source consulting company Inverse of Montreal, Canada, took over development of the project around 2006. In May 2022, email services provider Alinto of Lyon, France, became the new commercial steward of the project.
