A team with the privacy set to “public” allows all the Univ. members to access your messages/files post/uploaded to it. To enhanced security, all public teams will be set to “private” by system administrator,　unless you name it end by “-public” to assert that it is “public” on purpose.

There have been instances where teams created using platforms like Teams and SharePoint inadvertently had their privacy status set to public, resulting in the exposure of files containing personal information to all students and staff across the campus.
To enhance security, administrators have mandated that only public teams with “-public” appended to their names are permitted. Any public team lacking the “-public” suffix in its name will be promptly switched to private by the Microsoft 365 administrators upon discovery.
※Since February 5, 2026, “-group” has been automatically appended to the end of group names. Even when changing a group to public, only “-public” needs to be added manually.

For guidelines on modifying the team’s name and privacy status, please refer to Notes on the scope of file disclosure on Microsoft products (Teams, OneDrive, etc.).
