Hello,

I'm trying to fully understand the behaviour of the External Collaboration / Guest Invite settings with "Member users and users assigned to specific admin roles can invite guest users including guests with member permissions".

How is it possible for a guest to invite another guest when only team owners can invite guests to a team and guests cannot be owners?

IIS_2602

    Selecting this option does NOT allow guests to invite other guests. Only the first option, Anyone in the organization can invite guest users including guests and non-admins (most inclusive), allows that. Refer to the official documentation for more details, including how the invitation process works: https://learn.microsoft.com/en-us/entra/external-id/external-collaboration-settings-configure

    Do note that those settings are not specific to Teams, there are many other methods which can be used to invite guests. A guest added to another tenant can for example access the Entra ID portal and use the Invite external user functionality therein, if allowed by the tenant's configuration.
