Mattermost, alternative Linux à Microsoft Yammer

Notre avis

Mattermost can replace Microsoft Yammer for most internal communication needs, especially in organizations that prefer self‑hosting and want tighter integration with developer tools. It offers threaded messaging, file sharing, searchable history, and mobile/desktop clients. It lacks some of Yammer's enterprise‑wide social features like organization‑wide polls and built‑in analytics, so it fits best for teams that value control and extensibility over those specific Yammer extras.

Ouvrir vos fichiers Microsoft Yammer

Yammer does not expose a proprietary file format; content is stored as posts and attachments on the service. Mattermost can import plain‑text or markdown archives, but there is no direct import tool for Yammer archives. If you have exported data from Yammer (e.g., CSV or JSON), you would need to write a small script using Mattermost’s API to recreate the messages.

Passer de Microsoft Yammer à Mattermost, étape par étape

  1. Export Yammer data using the Microsoft compliance export tool (CSV/JSON).
  2. Set up a Mattermost server (Docker, package, or Flathub) and configure LDAP/SSO if required.
  3. Create equivalent teams and channels in Mattermost to match Yammer groups.
  4. Write or use an existing script to post exported messages via the Mattermost API.
  5. Upload any attached files to the appropriate Mattermost channels.
  6. Notify users of the new platform and provide login credentials.
