With the iPad connected to iTunes and selected, go to the Info tab. Most of the way down there is an option to sync notes. Check it and see if Outlook is an option.
If it is, it will only sync when you sync the iPad to the computer, but that's the only option I know of at the moment.
Personally, I've migrated almost all my note taking needs to Evernote. There is an Evernote app for just about every device, and when that fails you can always use the web site.
