As you know, when you setup a meeting, your status is going to be always set to “Busy / In Meeting”.
Well, good news as now you can set your availability status when setting up a Teams meeting.
This capability is available in both Teams client and web browser – this is not (yet?) available on Teams mobile.
To set your availability status, just open your Teams client and create a new meeting, then use the Show as option to set your availability status
