The “Auto-Complete” list is a feature which displays suggestions for names and e-mail addresses as you begin to type them. These suggestions are possible matches from a list of names and e-mail addresses from the e-mail messages you have received/sent. You may want to import this list if you want to use Outlook on a new computer. The first part of this tutorial will show you how to locate and copy the current file on your computer. The second part will show you how to import it into Outlook on the new computer. This procedure also works the same for Windows Vista.
This will ONLY work for importing Auto-Complete List from Outlook 2007 into a newer version of Outlook (2010 or 2013). There is no need to import the Auto-Complete list if you use Outlook 2010 or newer. It is stored on your Exchange Server so that it is available on ANY computer you use Outlook on.
