You already thought about when the conference is deactivate or expirated?
Today, we’ll talk a little about conference lifecycle.
There are some phases, as:
Create a conference, activating a conference, deactivation and expiration.
When you click in meet now, the meeting is created and activate in the same time. This case, is the only case that this happens. When you click to schedule a meeting with Skype for Business plug-in in Outlook, the Outlook plugin or Lync/Skype for Business contact the Focus Factory in Skype for Business.
Focus Factory is a component that check the conference policy and responds with the conference/connection information.
Activation occurs when an authenticated user sign in or using a phone and the PIN is to join in the meeting. If you are using Skype for Business client, the authentication happens at the time of the singning in.
