The *.nk2 files are used by the Auto-Complete feature. Outlook's auto-complete feature attempts to be helpful by suggesting email names that are similar to what you're typing. A couple of keystrokes, an auto-complete suggestion, and you don't have to type the entire email name every time. Seems both simple and handy.
The *.nk2 file is hidden by default. The older versions of Microsoft Outlook were using the .nick file extension instead.
