Viva Engage (formerly Yammer) is an enterprise social networking service that is part of the Microsoft 365 family of products.
[4][5][2] The service began as an internal communication system for the genealogy website Geni.com[6] and was launched as an independent product in 2008.
Yammer is included in all enterprise plans of Microsoft 365, and evolved into Viva Engage as of February 2023.
Yammer won top prize at TechCrunch50, which allowed them to invest more money into the project.
The main feature set included profiles, profile photos for groups, following suggestions, and a product called "YammerFox", which was an extension for Firefox that alerted the end user when a message was received.
[11] In 2010, new integrations were launched in the application, such as polls, chat, events, links, topics, Q&A, and ideas.
[13] Yammer also released its SharePoint 2007 Integration and transitioned to Scala for its real-time work.
