Recently I wrote a few posts about How to Clear the Outlook Auto Complete Cache and How to Fix a problem where the Outlook Auto Complete cache was REALLY slow. BUT, what if you just want to disable the Auto Complete functionality?
The task is simple. Just follow these 3 easy steps for both Microsoft Outlook 2007 and Outlook 2003.
