New Feature: Teams Private Channels
Private channels in Microsoft Teams create focused spaces for collaboration within your teams. Anyone, including guests, can be added as a member of a private channel as long as they are already members of the team.
Right now, any team owner or member can create a private channel by clicking on the '...' next to your Team name and selecting Add Channel.
