OneNote Notebook in a Teams Channel
This article applies to: Microsoft Teams
If you'd like the benefit of full-featured note-taking in a Microsoft Teams channel, you can add a OneNote notebook. Everyone in the channel will be able to view and make edits, or in the case of pre-existing notebooks they don't yet have permissions for, they can request access right from the tab.
See Microsoft's documentation to find out how to add a OneNote notebook to a teams channel.
