More… Less. Add real-time chat, virtual meeting capabilities, and extended collaboration features to your SharePoint team site by adding Microsoft Teams. Team sites that are connected to a Microsoft 365 group in SharePoint can easily add Microsoft Teams. Team sites that are not already connected to a group will first need to connect to a Microsoft 365 group before they can be added to Microsoft Teams.
