Microsoft Stream 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 timecodes in comments and descriptions to refer to specific points in a video and discuss with colleagues.
Microsoft Stream is a secure video service so you can manage who views your video content and determine how widely to share within your organization. Secure application access is enabled by Azure Active Directory, a recognized leader in identity management systems, to protect sensitive corporate content.
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.
