As a Stream Deck user mainly for work meetings (plus the odd video), I too was mortified when Microsoft killed the Teams API.

I found mention of MuteDeck on a Stream Deck "best plug-ins" site and haven't looked back.

The app uses a novel way of working with a Teams meeting even if it isn't selected or in the foreground, plus provides the current status of features like muting and camera that no hotkey could ever do.

I also had an issue while evaluating the plug-in and the issue was sorted within hours over the online chat. Totally brilliant support!

Every unhappy Teams user with a Stream Deck needs this app, with the benefit it also works with other conferencing tools when you have to use them with third parties.

Superb all round!
