What is Office 365 Video
Office 365 Video is an intranet website portal where you can post and view videos. It's a streaming video service that is available with SharePoint Online in Office 365.
It is a great place to share videos of executive communications or recordings of classes, meetings, presentations, or training sessions, for example. Office 365 Video displays a thumbnail image of each video on the site. You just select a thumbnail to view a particular video.
