The Inverse Team is pleased to announce the immediate availability of SOGo 3.1.2. 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, responsible Web-based interface aligned with Google Material
   Design guidelines
 * 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.
