Additional features, settings, or issues not covered by specific Microsoft Teams categories
To have the Webinar Feature available you need to run a few PS commands:
Set-CsTeamsMeetingPolicy -Identity Global -AllowMeetingRegistration $True
Set-CsTeamsMeetingPolicy -AllowPrivateMeetingScheduling $True
Set-CsTeamsMeetingPolicy -Identity Global -WhoCanRegister "Everyone"
Set-CsTeamsMeetingPolicy -AllowEngagementReport Enabled
see https://learn.microsoft.com/en-us/microsoftteams/set-up-webinars and
https://learn.microsoft.com/en-us/microsoftteams/teams-powershell-install (to enable the PS to connect)
However, at my tenant (region of my tenant Germany), I have different licenses assigned to users.
At the E3 plan, there is a drop-down that clearly shows "Webinar" to start the settings for an MS Teams Webinar.
But users with a Business Standard or Premium plan do not have a drop-down next to schedule a new meeting.
So I wonder if the way to set up an MS Teams Webinar is simply different with a Business plan vs. E3.
My assumption is, you can turn a "regular" meeting by enabling a registration page into a Webinar. At least it looks like this because while I was testing with the Business plan user that worked and I was able to set up a webinar. This is unconfirmed by Microsoft so far and there is no documentation. All documentation that I found show that next to scheduling a Webinar there is always a Live Event feature option, this however, is only available in enterprise licenses as the E3 plan.
