How is Microsoft Viva Connections different from Yammer Communities?
Yammer continues to be the social and community fabric across Microsoft 365, where employees can connect and have conversations around a topic, interest, or event. Microsoft Viva Connections builds on the conversations happening within Yammer communities by combining them with company resources, tasks, sites, and news from across Microsoft 365 and folds them into a single, personalised employee app.
Essentially, Yammer is a source of community content that is aggregated into Viva Connections, so everyone can stay on top of what is important to them and stay in the flow of work.
