Change moderator roles and settings in a channel in Microsoft Teams

By default, non-private channels are unmoderated, meaning anyone can post, react, and reply to posts. Team owners can set moderation roles for a channel to control this. Owners can also add team members as moderators. Establishing moderators can be helpful if you want to create, for example, an announcements channel, or a channel devoted to a specific topic.

Moderators can:

Post to a channel, and react and reply to posts in a channel
Add and remove team members as moderators
Control whether team members can reply to existing channel messages and whether bots and connectors can submit channel messages

Note: Channel moderation is available for standard channels on Teams for desktop or web. It's not available for the general channel or private channels.

Go to the channel, select More options > Manage channel.
Under Who can start a new post?, select Everyone except guests can start a new post.
