Mattermost vs. Microsoft Teams: eine gute Linux-Alternative?

Mattermost als Linux-Alternative zu Microsoft Teams

Aktualisiert am 19. Oktober 2026

Unser Fazit

Mattermost can replace Microsoft Teams for teams that need a self‑hosted, open‑source chat and collaboration platform. It covers real‑time chat, threaded conversations, video/audio calls, file sharing, and user/group management. It is best suited for developer teams or organizations that want full data control, CI/CD integration, and API‑driven automation. However, it lacks native Office 365 integration and the polished UI/feature set of Teams, so it may not satisfy users who rely heavily on Microsoft productivity tools.

Ihre Microsoft Teams-Dateien öffnen

Mattermost does not natively open or export Microsoft Teams files such as .msg or .docx. Users must rely on external tools (e.g., LibreOffice, Google Docs) to view or edit these files and then upload them to Mattermost. Exporting chat history from Teams into a format readable by Mattermost is not supported directly.

Häufige Fragen

Does Mattermost support video calls the same way Teams does?

Mattermost offers video and audio calls, but the implementation is less mature than Teams. It works well for small to medium groups, but large meetings or high‑definition video may experience quality issues.

Can I use Mattermost with my existing Office 365 documents?

Mattermost can host Office files, but it does not integrate with Office 365 for real‑time co‑editing. Users must open documents in Office or LibreOffice and then upload them to Mattermost.

Is Mattermost secure for enterprise data?

Yes. Mattermost is self‑hosted, giving full control over data. It supports encryption at rest, LDAP/AD integration, and compliance features, but you must configure and maintain the server yourself.
