Macbook Air M1 overheating when using camera for video call

The M1 Air has no fans to cool it, just radiational cooling via the case. Yes, it will get hot with video calls.

There is no fix other than to use a shorter video call timeframe, or possibly not using Microsoft software on Mac — and that may not be possible. You are driving the CPU and GPU cores bonkers and that produces heat. That sounds exactly like what I was experiencing years ago with Skype video calls on Intel hardware. Fans and heat dropped off immediately after the video call.

One very general thing that can assist a laptop’s radiational cooling is, when possible, to run the laptop on a grated-panel that raises the laptop a centimeter or so off the surface. That extra exposure of the laptop’s entire underside to air-circulation can really help.

This sounds like completely normal for the MacBook Air, that only features passive cooling, so the MacBook Air does not have any fans on board to help it cool. Software like Microsoft Edge And Teams have a big impact on the processor, to it will become hot with no active cooling, there is no way around that
