We acknowledge the customer demand for Private Channels and have been hard at work on it. Private Channels is currently in preview with a select group of customers. We expect to release the feature to the public later this Fall, and will update here when we are starting to roll out to all customers. We appreciate all the feedback you have provided to us on this forum and thank you for your patience.

Will private channels allow me to add users to the private channel without them being a member of the team?
We acknowledge the demand for this capability and are exploring the best possible solutions to enable this.
