Teams settings worth knowing
- Camera switches greyed out or missing in Teams? Your organization's policy may block video — ask your IT admin.
- Settings → Devices → Noise suppression: set it to Auto or High if the 5-second recording here shows a lot of background noise.
- Settings → Devices → Adjust brightness and Soft focus improve a dark or harsh picture.
- Light in front, camera at eye level, blur or replace the background if your room is busy.
