Conversations involving multiple participants, allowing collaboration and information sharing in Teams
Dear Chris,
As a forum moderator, I am not able to review your organization's Teams settings or chat membership to diagnose and fix this for you. My role here is limited to providing general guidance you can apply from your side.
Reports sent through Feedback > Report a problem go to the product team, but they don't create a support case, so you usually won't get a personal reply. Since this affects your class every day, a support case is the better way to get it investigated. I recommend that the Global Admin in your organization create a service request with Microsoft Support. A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin. If you don't know who your IT administrator is, please refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support
For additional assistance, use this link to find the appropriate contact number from your region: Contact Microsoft customer support | Microsoft Support
I hope this information is helpful and provide you with a clear path forward. Should you have any further questions or need additional assistance, please don't hesitate to reach out. I'm always happy to help. Have a wonderful day!
