How is Microsoft Viva Connections different from Yammer Communities?

Viva Engage (formerly 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 Viva Engage 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, Viva Engage 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.
