About Microsoft Stream Trouble
Dear Students, Faculty and Staff
This is an announcement from the Information Network System Division.
Subject: Trouble with Microsoft Stream
Since yesterday, there has been a problem with Microsoft Stream.
We are currently investigating the issue, and would like to inform you of the current situation.
Status of the problem:
There is a problem that students are unable to view the video uploaded to Microsoft Stream even after setting the access permissions to allow only those who are enrolled in the class to view the video.
However, this setting is not reflected and students cannot view the videos.
Status of investigation:
We have created a class group as a class template in Microsoft Teams.
The above issue has been occurring since this week when a group with the visibility: HiddenMembers parameter is set to a group created using this class template and set as a Microsoft Stream permissions group.
We are currently inquiring with Microsoft about whether or not the specification has changed and whether or not there is a problem.
What to do for the time being:
If the content of the class video does not contain copyright, you can check the "Allow everyone in the company to view this video" checkbox in the access permission settings, and all students will be able to view it.
We apologize for any inconvenience this may cause.
We will post an announcement on the Center for Science Information website as soon as the situation progresses.
