A freeware option that I used to use and still comes in handy is called NK2Edit from NirSoft, it does handle newer data just follow the instructions. Has the advantage of being able to edit the autocomplete data as well.
There are also things you can do like importing nk2 files by launching outlook with the /importnk2 switch. Slipstick has a lengthy writeup that covers all sorts of different issues and how to deal with them in different versions of outlook. Read this.
