Check if the device you are using currently has a webcam installed. If you are not sure, open the Start menu and type “Camera“.
Open the Windows Camera App.
If this message appears, either you do not have a webcam, or the webcam is broken/not installed properly. Check all connections/wires to the webcam and your computer.
(NOTE: Only ONE application can use the Webcam at a time, so MAKE SURE YOU CLOSE THE WINDOWS CAMERA APPLICATION BEFORE USING MICROSOFT TEAMS.)
