Sending a OneNote Note via Outlook E-Mail
You can send a Microsoft Office OneNote 2007 note via Microsoft Office Outlook in one of two ways:
If the recipient has Office OneNote 2007, click File, and then click E-mail. Office OneNote 2007 will open your Outlook (2007 or 2003) e-mail client and attach your notes as a .one attachment.
If the recipient does not have Office OneNote 2007, you can paste OneNote notebook content as HTML into the body of an e-mail message in Outlook.
