Add a fully interactive Yammer experience to Microsoft Teams. Yammer communities connect the organization, enabling you to engage with leaders, watch live events, and stay up-to-date with news and announcements. Communities also enable people to share knowledge, ask questions, get answers, and build relationships across teams and organizational silos. Add the Yammer app and pin it to the navigation rail. It’s Yammer—in Teams. This is an enterprise app that requires a license to use. A Yammer subscription is required to use the app.
