ACTION REQUIRED by May 2, 2023
Message Summary
With the launch of the new webinar experience, we introduced a new events policy.
In order to ensure smooth transition to the new webinar experience, we temporarily continued the old webinar policy setting of AllowMeetingRegistration in controlling the availability of the new webinar. Now with successful introduction of the new webinar, we will be decoupling the settings that control the availability of the old (via AllowMeetingRegistration in meeting policy) and the new (via AllowWebinar in events policy) webinar.
When this will happen:
This change will take effect on May 3, 2023.
How this will affect your organization:
The current state of enforcement with coupling of AllowMeetingRegistration and AllowWebinar controlled the behavior of the webinar entry point in New Meeting dropdown in Teams Calendar. Below is summary of the current state and changes this will bring highlighted in red if no action is taken:
By decoupling:
AllowMeetingRegistrationwill only control whether require registration option is available in Teams meetings. Availability of require registration option is not impacted by this change.AllowWebinarwill only control whether there will be the webinar entry point with the new webinar experience under new meeting dropdown in Teams Calendar.
You can configure the new events policy using Powershell cmdlets: New-CsTeamsEventsPolicy, Set-CsTeamsEventsPolicy, Grant-CsTeamsEventsPolicy, Get-CsTeamsEventsPolicy, Remove-CsTeamsEventsPolicy.
What you need to do to prepare:
If you want your users to still have a webinar entry point to create webinar, ensure AllowWebinar is set to ON. Note that users will be using the new webinar experience with the entry point and not meeting with registration moving forward.
If you want your users to only use meeting with registration and not the new webinar, you need to set AllowWebinar to be OFF and AllowMeetingRegistration to be ON. Note your users will not see a webinar entry point and will have to set require registration setting in a meeting.
