It's finally here, the new Yammer look is rolling out in May. This is a face-lift I know many of my customers and partners have been waiting for, and the preview is about to hit your tenants soon. The preview feature will not be available by default, but will require the admin to set a policy. 
Once the feature his your tenant, admins will have a new tab in the network configurations where the following options will appear:
- Staying on the Classic Yammer
- Enabling Preview as opt-in
- Enabling Preview as default setting
Preview opt-in is my favorite choice, as this will allow users to control their own experience.
