Mattermost als Linux-Alternative zu Microsoft Teams (legacy)

Aktualisiert am

Unser Fazit

Mattermost can replace Microsoft Teams (legacy) for teams that need a self‑hosted, open‑source solution. It covers core chat, channel organization, file sharing (with version history), and basic audio/video calls, and works on Linux, Windows, macOS, Android, and iOS. Teams that rely heavily on Microsoft‑specific integrations (Outlook calendar, SharePoint, Teams bots) will find gaps, but developers and small‑to‑medium businesses that prefer control and extensibility will benefit.

Ihre Microsoft Teams (legacy)-Dateien öffnen

Mattermost stores files in a database or filesystem; it does not natively import Teams .msg or .docx attachments. Exporting Teams files to a shared folder and uploading them into Mattermost is the usual workaround. Direct conversion of Teams chat history to Mattermost format is not supported.

Von Microsoft Teams (legacy) zu Mattermost wechseln – Schritt für Schritt

  1. Export Teams chat history to CSV or JSON using the Microsoft Graph API.
  2. Export Teams files to a shared folder or OneDrive and download them locally.
  3. Set up a Mattermost server (self‑hosted or cloud) and create the same channel structure.
  4. Upload exported files into the corresponding Mattermost channels and use the versioning feature to keep history.
  5. Import chat history by using Mattermost’s import API or a community tool, mapping user IDs appropriately.
  6. Verify permissions and test audio/video calls before decommissioning Teams.
