There's a great range of free Powertools for OneNote
John Guin has posted an interesting article listing the OneNote Powertools - they are free to download (and use) and are well worth a look. John works as a member of the OneNote test team at Microsoft.
There are tools for transferring information to OneNote Mobile, migrating information from Outlook and manipulating data within OneNote.
Thanks to the team for creating them as I gather they wrote the tools in their own time.
