Delete a Channel in Teams

Team owners get to decide which team members can delete and restore channels.

Tip: If you’re considering deleting a channel because you’re being inundated by notifications about new messages, you can instead just turn off notifications.

To delete a channel, go to the channel name and click More options More options button > Delete this channel.

Keep in mind that once you delete a channel, you also lose its entire conversation history. However, the OneNote sections associated with that channel will still show up on your team's SharePoint site.
