Compatibility & Requirements
Microsoft have recently removed support for virtual webcams in MS Teams for macOS, therefore ManyCam is not able to connect to their app.
In the meantime, you can try the workaround presented in this thread on our Forum.
Make sure your MS Teams is up-to-date. You can download the latest update here.
How to connect ManyCam with Microsoft Teams
