The Inverse Team is pleased to announce the immediate availability of SOGo v2.3.21. This is a minor release of SOGo which focuses on small new features and improved stability over previous versions.

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 (Mac OS X and iOS) and Microsoft Outlook.

SOGo is standard-compliant and supports CalDAV, CardDAV 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, 2010, 2013 and 2016
  • Two-way synchronization support with any Microsoft ActiveSync-capable device (Apple iOS, Android, Windows Phone, BlackBerry 10) or Outlook 2013/2016
  • Excellent native integration with Apple software (OS X and iOS) and Android-based devices

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