Hello,
you can create a workspace "myworkspace" on office live,
and create in onenote a new shared notebook (select the radio box :
"sharepoint place") and choose the location like this :
"http://myaddress.com/myworkspace/"
that's all ;)

> Can I use Office Live Workspace to keep my OneNote files synchronized?
>
> If so, how? If not, why not?
>
> Thanks in advance.
