I can add any external M365 user to a Live event?!

[Thomsch]

I just tried to add some external users to a Teams Live event and it works just fine. These users are no guests at the Tenant and no federation was negotiated with the domain. Is that a normal behaviour? Why would I create guest users if it's possible without it?

@Thomsch  the reason this is true maybe these options are not turn off or configure the same way to collaborate with external organizations is allowed.

Collaborate in Teams with users external to the organization this article will give you overall details information;

Hi @Thomsch , I thought you just had to add them as a guest user in your tenant if they didn't have an Office 365 account themselves?

@David Gorman I'm trying all possible options here. And since the guest user path is not working, I found out that I actually don't need a guest account at all.

Hi @Thomsch I think this thread might have gotten a little off-track from your original question.  You're correct that you don't need to create guest accounts - you just send the attendee invitation* link to whomever you want to invite to the event, and make sure the permissions are set correctly (see doc below).

*Producers and presenters will get a different link.
