If you're using Outlook I assume you've got Onenote too. Create a daily meeting in outlook titled diary or whatever, and when you want to take notes open the meeting for today and use the meeting notes feature to take notes. The only issue I see with this is that it might not organize the daily notes by date in Onenote, but there are decent features for moving pages around and reorganizing them. Plus everything is searchable and if you want you can save the whole notebook in skydrive and open them from your phone. Say what you will about MS, in my day-to-day work OneNote is the best thing since sliced bread.
