Yammer Is Now Activated by Default and Integrated into Azure

Yammer is now activated automatically for Office 365 users instead of requiring an extra registration and activation process.  Microsoft hopes this will encourage users to adopt Yammer as a social networking tool. 

Yammer also also now been fully deployed within the Azure data centers globally and therefore is now part of the Office 365 Trust Center – previous Yammer was not included which from a compliance perspective was a challenge from some regulated organizations.
