My Tenant finally received the Yammer Enterprise update! Here are the steps to activate Yammer Enterprise in Office 365.
From the Portal main page click on the link under Included Services
Click on the link to confirm activation of Yammer Enterprise
Select the domain you would like to have Yammer Enterprise Activated on, it is that simple.
When I started my Activation last Wednesday it stated it would take 1 to 30 minutes, well unfortunately it took much longer, about 4 days.
During the Activation the Dashboard snapshot showed provisioning… for Yammer Enterprise
