Rumors suggesting Microsoft was in talks to purchase Yammer were true. The Redmond-based company on Monday announced it has acquired the four year-old company, which currently provides enterprise social networks to more than 5 million corporate users, for $1.2 billion in cash. Yammer will join the Microsoft Office Division.

"The acquisition of Yammer underscores our commitment to deliver technology that businesses need and people love," Steve Ballmer, Microsoft CEO, said. "Yammer adds a best-in-class enterprise social networking service to Microsoft's growing portfolio of complementary could services."

The acquisition, which is still subject to regulatory approval, will look to further Yammer adoption. Microsoft will implement the service in Microsoft SharePoint, Office 365, Microsoft Dynamics and, of course, Skype. Concurrently, Yammer will stay committed to its standalone service.
