Microsoft are now making it possible for you to set Teams meeting defaults in your company, so that only meeting organisers can bypass the lobby.
How does this affect me?
Currently, the default setting for “Automatically admit people?” is Everyone in your organization. The other two options are Everyone in your organization and federated organizations or Everyone (no restriction).
Although you can limit direct meeting access to the meeting organiser, you cannot currently make that a default setting for a given user or set of users.
With this change, you will have a fourth option. You will be able to set “Automatically admit people” to Organizer only (which is the most restrictive).
Once this is your default, it applies to all new meetings you create. It’s worth noting that you can select Meeting options in the meeting invitation to change this setting for each meeting you schedule.
This update will roll out at the end of August and be completed by early September.
