Turn off Yammer access for Office 365 users

Yammer is included in most Office 365 subscriptions. You can disable Yammer for individual users, or for all users in your tenant. To keep your users from accessing Yammer, you have to first turn off their ability to sign in to Yammer with Yammer credentials, and then disable the Yammer service in their license.
