As of June 21, 2018, Microsoft Teams for Surface Hub is now in preview for Windows Insiders. https://www.windowscentral.com/microsoft-teams-surface-hub-enters-preview-insidersPaul commented
This is a gotta have. We are emphasizing teams as our primary communication tool in our global organization. We are installing surface hubs in each location. We must have this for our strategy to work!
We are still considering this feature for future releases, and will continue to update the status when it changes.
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.
