Why is my Microsoft Classroom not allowing me to mute a student’s microphone?

1. Check if you have any active microphone devices connected to your computer.
2. Verify that you have the latest version of Microsoft Classroom installed on your device.
3. Confirm that your web browser is updated to the latest version.
4. Ensure that you have granted the required permission for your microphone.
5. Restart your web browser and try again.
