You, as the Teams meeting organiser, can have greater control over the meetings by enabling a new lobby setting where only Calendar meeting invited users will be able to join directly.
How will this effect you and your organisation?
If you are the meeting organiser, you will be able to ensure that only calendar meeting invited users can bypass the lobby after they schedule a new meeting. You can do this by changing the meeting meeting ‘Who can bypass the lobby’ to ‘People I invite’. Anyone else with the meeting invitation will be sent to the lobby
When can you expect this?
Roll out is expected to begin in early February and will complete mid February.
