Outlook 2010 Auto-Complete cache reset

I need to remake the auto complete cache on a computer, and I'm using the method of sending a blank email to all of my contacts while disconnected from the internet. I tried this and it's worked with a list of a few contacts (about 5), but I'm wondering if Outlook might crash when I attempt this with the full sized contact list, which is about 100 or so total entries.

Could anybody shed some light on this issue? I'd just like to avoid any problems with this theory before I implement it on a larger scale.

Thanks so much! That should solve my issue with much less hassle.
