The Inverse Team is pleased to announce the immediate availability of SOGo 2.2.0. This is a minor release of SOGo which focuses on improved stability over previous versions and the addition of the Microsoft ActiveSync protocol support.

What is SOGo

SOGo is a free and modern scalable groupware server. It offers shared calendars, address books and emails through your favorite Web browser or by using a native client such as Mozilla Thunderbird and Lightning, Apple Calendar and Address Book (OSX and iOS) and Microsoft Outlook.

SOGo is standard-compliant and supports CalDAV, CardDAV, GroupDAV and reuses existing IMAP, SMTP and database servers - making the solution easy to deploy and interoperable with many applications.

SOGo features:

  • Scalable architecture suitable for deployments from dozen to many thousand users
  • Rich Web-based interface that shares the look and feel, the features and the data of Mozilla Thunderbird and Lightning
  • Improved integration with Mozilla Thunderbird and Lightning by using the SOGo Connector and the SOGo Integrator
  • Native compatibility for Microsoft Outlook 2003, 2007 and 2010
  • Two-way synchronization support with any Microsoft ActiveSync-capable device (Apple iOS, Android, Windows Phone, BlackBerry 10) or Outlook 2013
  • Excellent native integration with Apple software (OSX and iOS) and Android-based devices

and many more! SOGo and our connectors are completely free.
