Add a GAL hidden user to a Teams
I have some users GAL hidden members that I would like to add as a Teams members. In Outlook, even if a user is hidden, you can send him a mail if you write the correct address, this appears not to be the same trying to get a hidden member to Teams, even if you write the full address it is impossible to add him to a Teams. Does anyone know a workaround or a way to do it?
