Windows 8.1 Searched here and Google to find how to get OneNote to appear in Outlook 2007. In Tools>Trust Center>Add ins, Onenote is in the list of active addins ("Onenote notes about Outlook items"). FWIW, Onenote doesn't appear in Excel or Word. Tried opening/closong Outlook. Tried rebooting PC. I found one article saying Onenote should appear in "Programs and Features." It does not. Help please.
