Q: What are document conversations in SharePoint Online and OneDrive, and how can I make the best use of them?
A: Document conversations is a new feature that provides the social collaboration capabilities of Yammer into SharePoint Online and OneDrive. Users can leverage this new feature to share ideas and their expertise in the documents that they are currently editing or viewing.
Document conversations works by opening a file in SharePoint Online or OneDrive, where you should see a file on the left with a Yammer conversation pane on the right-hand side. You can collapse or expand the pane as needed. Within this pane, you can post messages, mention coworkers, or publish to a Yammer group, in public or private.
Document conversations are in the process of being rolled out to customers this summer. To leverage document conversations, you'll need to make sure that Yammer is enabled as your primary social network.
