Microsoft today provided new information about how it will be integrating Office 365 Groups into its Yammer enterprise-focused social network. The Yammer Enterprise service tier will be going away on January 1, 2017. But Yammer itself will remain available, and there are many levels of integration with the Office 365 services, reports VentureBeat. From the report: It will be possible for people to make Word, Excel, and PowerPoint documents using Office Online within Yammer, and it will be easy to go from Yammer to a shared OneNote notebook or the Microsoft Planner project management tool. Team members will be able to select existing files from OneDrive and SharePoint and share them with colleagues in Yammer, too. And Yammer teams will get their own SharePoint sites, enabling them to build wikis and blogs. Microsoft will be rolling out the integration in phases, with the first phase beginning later this year, the Yammer team said in a blog post. The first Yammer customers to get it are those whose users log in with their Office 365 identity. And Microsoft will initially be targeting organizations with a single Yammer network connected to one Office 365 tenant.
