SOGo

Self-Hosted

Open-source groupware solution for email, calendars, and contacts

Overview

SOGo is an open-source groupware platform offering integrated email, calendar, address book, and task management. It supports standard protocols like CalDAV, CardDAV, IMAP, SMTP, and ActiveSync, ensuring compatibility with mobile devices and desktop clients (Outlook, Thunderbird). Deployable via Docker, pre-built packages (Debian/Ubuntu/RHEL), or source, it scales from small teams to enterprises with multi-tenancy and LDAP/AD integration.

Frequently Asked Questions

? Is SOGo hard to install?

SOGo offers Docker deployment (simplest option) and pre-built packages for major Linux distros. Docker reduces setup complexity, but package installs require configuring web servers (Apache/Nginx) and databases (PostgreSQL/MySQL). Basic server admin knowledge is helpful for optimal setup.

? Is it a good alternative to Microsoft Exchange?

Yes—SOGo supports ActiveSync (for Outlook/mobile) and core groupware features, making it a strong open-source alternative. It lacks advanced Exchange features like Teams integration but provides self-hosted privacy and no recurring costs.

? Is SOGo completely free?

SOGo is open-source (GPLv2 licensed) and free to use, modify, and self-host. There are no subscription fees, though paid enterprise support is available from third-party vendors if needed.
