Yammer

Yammer is a Microsoft-hosted social networking service for organizations that offers collaboration spaces with groups, conversations, and data sharing that are similar to public social networking services, such as Facebook and Twitter. The service’s roadmap focuses on integration with other Office 365 services, which will open it to many more users. However, it also faces competition from Teams, Delve, and other Office 365 services for Microsoft developer resources.

Yammer Overview

Yammer sites and groups enable users to communicate with one another using microblogging (threaded conversations using short messages as on Twitter) and instant messaging (IM). Users can also share files through the service. Users track communications and other activity from people and topics of interest on an automatically compiled discovery feed (newsfeed) page: they follow other users, topics, and files and receive notifications about them on the feed. Yammer groups can range from secret (visible only to invited members) to public. External messaging and external group features enable users outside of an organization to collaborate with the organization’s Yammer users.
