Groups in Microsoft Stream are both a way to organize videos and to control access to videos. Groups allow you to define a set of owners and members of a group. Each group gets its own mini video portal, with a highlights page showing trending and new content within the group. You can even further organize your group's videos by creating channels within the group. You can put a video into one or several groups to help viewers find it more easily.
Office 365 Groups
If you are an Office 365 customer, groups in Microsoft Stream are built using Office 365 Groups. When you make a group in Microsoft Stream, it creates a new Office 365 Group that can be used across Office 365, giving the group an email address, calendar, site, etc. If you already use O365 Groups in your organization, you can start using those groups in Microsoft Stream right away.
Deleting a group in Stream will also permanently delete the Office 365 Group, and everything associated with the group. This includes videos, conversations, files, and content for all the Office 365 Group enabled services like Outlook, SharePoint, Teams, Planner, Yammer, etc.
[AZURE.NOTE] If Office 365 Groups are created or changed in other O365 services, there could be a ~1-2 hour delay before those changes show up in Stream. Likewise, Groups created in Stream could take sometime before they show up other places in O365, depending on the other application.*
When you create a group in Stream, you set if the group is companywide or not. This determines who has access to see content inside the group.
When "Make this group companywide" is checked for a group, the group is public inside the organization. Use this type of group when you want to broadcast out information to most of your company.
Characteristics of companywide groups:
Anyone in your company can join without being added by a group owner
Everyone in the organization will be able to see the videos within these groups
When "Make this group companywide" is not checked, the group is private. Use this type of group when you want to limit access to who can view videos within the group.
Characteristics of private groups:
An owner of the group will have to add or approve members who join the group
Only group members will be able to see videos within the group
Owners & Members
Owners Owners of the group will get full control over the group and any videos owned by the group. They can edit the settings of the group, create/delete channels, and delete the group itself.
Members In Microsoft Stream, we have a Stream only setting that controls if members are contributors to the group or they are viewers only. This is controlled by the "Allow members to contribute" check box on the group.
If "Allow members to contribute" is checked, the members of the group will be contributors to the group. They will be able to create/delete channels, and add video to the group, and modify videos owned by the group.
If "Allow members to contribute" is not checked, the members of the group will be viewers of the group. They will only be able to view videos with this group.
Channels are an organization method for videos, but not a permission method. Channels don’t have any permissions on their own. If viewers follow your channel, they can get updates on new videos added to it. You can put a video into one or several channels to help viewers find it more easily.
When you create a channel, you decide whether it’s a companywide channel that anyone in your organization can add and remove videos from, or if it’s a group channel where you can limit contributors.
Companywide channels are great for organizing videos by topics and providing a way for community-driven content curation.
Characteristics of companywide channels:
Can be seen by everyone within your company
Everyone within your company can add videos or remove videos from them
Only the creator of the channel (and Stream admin) can edit the channel itself
Only videos that have "Allow everyone in your company to view this video" checked can be added to companywide channels
Groups channels are great for adding further organization of videos within a group and when you want to determine who can see and who can upload videos to a channel.
Characteristics of group channels:
Inherits the permissions from the group they are contained in
All contributors to a group can create channels, add videos to them, remove videos from them, and edit settings about the channel
There are lots of ways to grant permissions and organize videos in Microsoft Stream. With the combination of companywide channels, groups, and channels within groups, you can customize Microsoft Stream to be just right for sharing your videos.
