Hi @kastenjc
The official documentation states: Messaging policies are used to control which chat and channel messaging features are available to user.
This means that if you configure this policy for a user, the settings in the policy will apply to both normal chats and channel chats, which is by design in Teams.
If you want to set up your channel independently from your normal chat settings, 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.
