Setting up future meetings with participants using Teams calendar or Outlook integration
To let external attendees join directly and start the meeting without the organizer being there, these settings must be in place:
- In the meeting’s Meeting options, set Who can bypass the lobby? to Everyone.
In Teams: Calendar > select the event > View event > Options > under Meeting access, change Who can bypass the lobby? to Everyone > Apply. - If the attendees are anonymous users or dialing in, they can still be held in the lobby until a verified participant joins, even when Everyone is selected, depending on the meeting policy set by the IT admin.
- To allow anonymous participants to start meetings, the IT admin must enable the policy for anonymous users to start a meeting. By default, Anonymous users and dial-in callers can start a meeting is Off, which means anonymous participants and dial-in callers always wait in the lobby until a verified participant starts the meeting.
- External access must also be enabled correctly depending on how those attendees join:
- Guest access in Teams for guests
- External access for people in trusted organizations
- Anonymous meeting join for anonymous participants If any of these are turned off, that type of external participant can’t join regardless of lobby settings.
So, turning off the waiting room alone is not enough. For external people to start the meeting themselves, the key combination is:
- Who can bypass the lobby = Everyone
- Required external access setting enabled for their participant type
- IT admin enables anonymous users to start meetings if they are joining anonymously
