Convert a channel to private

If a channel's conversation is better suited for a closed audience, it can be converted to private. This type of channel is best for discussions that shouldn't be open to everyone.

Bear in mind

Note: on the Enterprise Grid subscription, you can convert a channel to private from the org dashboard. Learn more about channel management tools.
