How this will affect your organization
There are no admin controls related to this feature. Users will see an invitation screen when added to a group chat by an external unmanaged Teams user. At this point they can choose to acknowledge the invitation or leave the group chat. Users will continue to have the option to block and unblock external unmanaged Teams users.
Users will not see this update if external access with unmanaged Teams users is disabled or if incoming chats from unmanaged Teams users are disabled.
What you need to do to prepare
If external access with unmanaged Teams users is enabled, consider notifying your users of this update. Visit this page for more information regarding external access settings with unmanaged Teams users.
