This is a question we run into often, especially when customers are migrating to a new computer.

Outlook 2003, and above, creates a file called outlook.nk2 that stores all of your entries that are typed into the “to” box. When you migrate to a new computer, you need to make sure this file is moved to the new computer. The file is located in the following directories:

  • Windows 7 and Vista – Go to drive:/user/AppData/Local/Microsoft/Outlook
  • Microsoft Windows XP – Go to drive:/Documents and Settings/user/ApplicationData/Microsoft/Outlook

And, enjoy the new computer!
