is it possible to add external contacts to chat part? I know that it is possible to add external people to the team. My case is different, I just need add people to chat. We are rolling out Teams to company but this is a limitation for end users. Most of them have a lot of external contacts (people outside of organization) in Skype for Business and also Skype contacts. Is there a way how to add external contacts (Skype and Skype for Business) just for chatting?
