FunOS

Microsoft Teams is a widely used communication and collaboration platform, especially in work and educational environments. While Microsoft does not provide an official Linux client anymore, an open-source community effort called Teams for Linux offers a native-like experience on Linux systems—including FunOS. In this guide, we’ll walk you through the step-by-step process of installing, launching, and even uninstalling Microsoft Teams on FunOS.

What is Microsoft Teams?

Microsoft Teams is a collaboration platform developed by Microsoft that combines chat, video conferencing, file sharing, and app integration in one place. It’s designed for teamwork and productivity and is widely used by companies, educational institutions, and organizations of all sizes. Teams enables users to:

• Send instant messages and create group chats
• Hold online meetings and video calls
• Collaborate on documents with Microsoft 365 integration
• Share files and workspaces across departments or teams

Although Microsoft has discontinued the official Teams Linux client, the open-source community maintains an unofficial client called Teams for Linux. This application wraps the web version of Teams in an Electron-based desktop app and brings a native desktop experience to Linux users.
