Microsoft Stream, which is a part of Office 365, is an Enterprise Video service where people in your organization can upload, view, and share videos securely. You can share recordings of classes, meetings, presentations, training sessions, or other videos that aid your team’s collaboration. Microsoft Stream also makes it easy to share comments on a video, tag time codes in comments and descriptions to refer to specific points in a video and discuss with colleagues.
Microsoft Stream also helps you organize content into Channels and Groups so it’s easier to find. Microsoft Stream works well with other Office 365 apps like Teams, SharePoint, OneNote, and Yammer, giving even more ways to discover more relevant content.
