Users cannot schedule meetings in private channels. This is by design in Teams.
When you click to schedule a meeting, Teams will prompt you that "Your admin has not enabled this feature." This is a UI error in Teams. It should be "Microsoft has not added this feature."
To get this feature more quickly, you can send a feedback directly to Microsoft Feedback to add it in future updates.
Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future.
Thanks for your understanding and support.
