Issue with guests reentering Teams meetings and bypassing the lobby
• Navigate to the Teams admin center
• Navigate to the tab “meetings” then “meeting policies”
• In there they should have a “global policy” that we can edit (they would just have to click it)
• From here Navigate to “participants & guest” and change “automatically admit people” from “everyone” to “everyone in the Organization”
• Then also change “allow dial-in user to bypass the lobby” to “off”
If the Guest user be admitted at the first he joined the meeting, then he left the call and rejoin. The Guest will automatically bypass the lobby, this is concerning from a security perspective. Please help on investigating it.
Thank you for your feedback! We have released a feature that if an anonymous or federated user is admitted into the meeting via the lobby, that user will go through the lobby for each subsequent rejoin. It does not matter if the user left on their own, was removed, or dropped from the meeting.

Also more than one person should be able to by-pass. Administrators and other presenters should be able to pop in and out of meetings without permission.
If they can bypass the lobby upon re-entry then students will be able to rejoin the link at anytime - this is not a good idea. they should only be able to re-enter if the "owner" or teacher/admins are in the meeting.

I volunteer for a very large youth organisation in the UK who are using Teams to engage with our young people. If the meeting is recurring and the attendee has attended a meeting in the series before (i.e. they were admitted through the lobby), they seem to be able to rejoin all future meetings without being put into the lobby which raises potential safeguarding concerns.
We really need this fixed so that all external guests are forced into the lobby before they are admitted to the meetings by the organiser or one of the other volunteers attending with an organisation-O365 account.

Hey guys! I think this feature could help solve some related concerns.
Rejoining and bypassing the lobby would not be possible if everyone landed in the lobby.
This has almost 700 votes and the team is working on it:

Can this be included in live events and team meetings please
This is almost the same issue as this: https://microsoftteams.uservoice.com/forums/555103-public/suggestions/40258888-stop-people-joining-a-meeting-after-the-allotted-t
When a meeting has passed it is possible to reenter that meeting and that may disturb the organiser.

Need to be able to hold people in lobby so that they can't enter or start the meeting without the meeting owner, this is a major security issue that needs to be fixed asap.
This is a big issue, we are trying to hold confidential meetings with staggered external participants and can't have people re-joining just because they want to when they've been removed.
Same issue recently. Organizer accidentally clicked accept on a guest. Realized the mistake and removed the guest from the meeting.
Kept popping back in and needing to be removed over and over.
A removed guest should be forced back to the lobby if they try to reconnect. Or have some sort of option to ban/temp ban.
Just found out this issue today, huge issue in education and trying to control guests.
This is a huge issue. If we remove a participant they shouldn't be able to auto join!
