Microsoft today announced a new social enterprise feature for Office 365 called “document conversations,” which puts the collaboration features of Yammer into Office apps. These conversations enable workers to comment on materials such as documents, images and videos from within the asset, without having to go to a social application. This will work with assets stored in SharePoint Online, in Office 365 or in OneDrive for business.

According to a blog post from Christophe Fiessinger, Microsoft group product manager on the enterprise social team, “When you open a file in your browser from your cloud store, you see the file on the left with a contextual Yammer conversation in a pane on the right. You can collapse and expand the Yammer pane as needed.”
