On March 19, day one of Microsoft's annual Convergence conference, company officials shed more light on how Yammer's enterprise social-networking technology will be integrated into Office 365 and SharePoint in the coming year-plus.
Last fall, Microsoft officials said in the "immediate future" Yammer and SharePoint would be unified via a single ID/sign-on, shared document-management capabilties and feed aggregation. In the longer term, the Softies said, the two would be integrated from an email, IM and video-conferencing perspective.
The ability to replace the SharePoint/Office 365 newsfeed with Yammer is coming this summer. According to Microsoft, some customers have been unsure as to whether they should use Yammer or SharePoint for their news feed. As of today, Microsoft's answer is "go Yammer" if possible, whether using Office 365 and/or SharePoint Online in the cloud or SharePoint on-premises.
Microsoft will provide guidance on how to replace the SharePoint newsfeed with the Yammer newsfeed in SharePoint Server on-premises this summer.
Single sign-on is coming this fall as part of an Office 365 update.
The user experiences of Office 365 and Yammer start to converge this fall. (A fairly blurry mock-up of what this means is embedded in this post above.) This is also when the new Yammer experience will add "rich document capabilities" and integration of the Office Web Apps' editing/coediting of Word, PowerPoint and Excel documents
