Yammer is the O365 enterprise social networking (ESN) service, commonly used for private communication within organisations but also able to be deployed in an extranet for collaboration with clients or suppliers.

Also known as “Facebook for Businesses,” Yammer is a social network for employees, allowing people to tag each other for direct messages, use hashtags for searchability, attach files to posts and to create groups/teams for collaboration.

A valuable communication tool, Yammer is best for informal, fast paced  communications, either organisation-wide or within a predefined group. Any ESN deployment must be undertaken with a clear strategy to ensure your platform is utilised within the organisation to build a positive, open culture and deliver business outcomes.
