SOGo enables Mozilla Thunderbird/Lightning, Microsoft Outlook, Apple iCal/iPhone and BlackBerry client users to collaborate using a modern platform. SOGo features include the ability to share calendars, address books and mails in your community with a completely free and open source cross-platform solution. Using the Funambol middleware and the Funambol SOGo Connector, it allows any SyncML clients to fully synchronize contacts, events and tasks with SOGo.

SOGo supports many standards such as CalDAV

 support is provided through an OpenChange storage provider. Users can share address books, calendars and emails with other SOGo users without relying on costly MAPI providers. The connectivity between Microsoft Outlook and SOGo is native as SOGo will act as a fully featured Microsoft Exchange server to Microsoft Outlook clients.

Features

SOGo reuses existing services such as Microsoft Active Directory, OpenLDAP, a SQL database, or even an IMAP server. By reusing those, SOGo prevents time-consuming data migration or directory services data duplication or synchronization problems. SOGo is very fast and uses few resources. SOGo is a compiled software so the required hardware footprint is very low and a single SOGo server can easily handle thousands of users.

From the user's point of view, SOGo can be accessed through its web interface, desktop clients or mobile devices.

SOGo's web interface features a lightweight AJAX interface available in over a dozen languages. Its modern look and feel mimics Mozilla Thunderbird and offers drag and Drop capabilities for contacts, events and mail messages for all modern web browsers. Single sign-on capabilities are also available using CAS, WebAuth or Kerberos.

Supported desktop clients are Mozilla Thunderbird with the Lightning extension, Apple iCal and Microsoft Outlook. The SOGo Connector and Integrator extensions for Mozilla Thunderbird are optional but they perfect the integration of Thunderbird with SOGo.

Mobile devices are generally handled through the Funambol middleware and the Funambol SOGo Connector. This allows any SynML-capable device to synchronize contacts, events and tasks with SOGo. Devices such Apple iPhone are handled natively in SOGo as the Apple iPhone OS supports CalDAV
