Meeting organizer isn't prompted for leader PIN when joining Skype for Business Online meeting

PROBLEM
When you use a Microsoft dial-in conferencing number to join a Skype for Business Online meeting as the organizer, you experience the following symptoms: 
  • You aren't prompted for your leader PIN.
  • Unauthenticated callers have already joined the call.
SOLUTION
To resolve this issue, disable the Allow unauthenticated callers to be the first people in a meeting. If not, then they will wait in the lobby until an authenticated user joins option in the meeting.
MORE INFORMATION
When you assign Microsoft as the provider for dial-in conferencing to a user, there's an Allow unauthenticated callers to be the first people in a meeting. If not, then they will wait in the lobby until an authenticated user joins meeting option.

Organizers of Skype for Business Online Meetings should use this setting when they want to restrict dial-in users from joining calls before a leader has joined the call or when they want users to be prompted to enter a leader PIN if a leader hasn't yet joined the call. Until a leader has joined the call, all other callers should wait in the lobby. 

The default value for new users of dial-in conferencing is Null, or $False.

Note The remote PowerShell parameter that corresponds to this setting is AllowPSTNOnlyMeeting.

When this option is set to $False (the default value for new users), the Allow unauthenticated callers to be the first people in a meeting check box is not selected, and dial-in conferencing behaves as follows:

  • If a dial-in user is first to join a meeting, they'll be prompted to enter a leader PIN. If they don’t enter a leader PIN, they'll be prompted to record their name (if the option to Ask callers to record their name before joining the meeting is set in Microsoft Bridge Options), and then the caller will be informed that the leader has not yet arrived and to please wait in the lobby until a leader joins.
  • When an authorized user joins the meeting, dial-in callers will be automatically admitted to the meeting. This setting is equivalent in behavior to PSTN Callers Bypass Lobby in Skype for Business Server.
When this option is set to $True, the Allow unauthenticated callers to be the first people in a meeting check box is selected, and dial-in conferencing behaves as follows:
  • If a dial-in user is first to join a meeting, they'll be admitted immediately because there's no requirement for an authenticated user to join the call first.
  • Callers will not be prompted to enter a leader PIN.
Important Meeting organizers should always end meetings by selecting End Meeting from the Skype for Business meeting control menu. To do this, click the ellipses at the lower-right corner of the meeting window, and then select End Meeting. This makes sure that the meeting ends, that no unauthorized users can join without the organizer, and that all users are removed from the meeting.
