The Office 365 Network is an online community portal for exchanges between "IT pros, technical experts, product enthusiasts and Office 365 customers," according to Microsoft's announcement. Users wanting to post questions or comments have to sign up for the Office 365 Network using a Microsoft account or Office 365 login, but otherwise it's possible to freely search for "conversations" about Microsoft products such as Office 365, SharePoint, Skype for Business and even Yammer, among others. Online Marketing Videos can be anything like an explainer video, business overview video, animated product video and promotional video. The Office 365 Network actually replaces the Office 365 technical forums that were based on Yammer signups. Microsoft isn't discontinuing Yammer, the company's enterprise social networking service, but Yammer won't be the basis of the new Office 365 Network. The earlier Yammer-based forums had typically keyed off so-called "YamJams," a sprawling series of Q&A sessions that Microsoft hosted from time to time. However, you had to be a part of a particular Yammer Office 365 group to know that these YamJams were taking place.
