AutoComplete is an Outlook feature which offers suggestions of e-mail addresses as you type them. These suggestions are possibilities from a list of names and e-mail addresses that you have previously typed, known as the AutoComplete list. You can copy the AutoComplete list from one computer to another.
Exit Microsoft Outlook before proceeding. The Outlook user data folder is hidden by default. You likely will need to show hidden and protected operating system files in Folder Options before you will be able to navigate to the necessary folders.
On your old computer, choose one of the following (assuming your user data is located on the C: drive):
Windows Vista, 7 or 8 - C:\users\username\AppData\Local\Microsoft\Outlook.
Windows XP - C:\Documents and Settings\username\Application Data\Microsoft\Outlook.
Right-click file profile name.nk2, and then click Copy.
Either send profile name.nk2 to yourself as an email attachment, save to a network shared folder you can access from your new computer or save it to removeable media.
Make sure Outlook is also stopped on the new computer.
On the new computer, choose one of the following:
Windows Vista, 7 or 8 - Save profile name.nk2 to C:\users\username\AppData\Local\Microsoft\Outlook.
Windows XP - Save profile name.nk2 in C:\Documents and Settings\username\Application Data\Microsoft\Outlook.
If the Outlook user profile name is different on the new computer, you must rename the profile name.nk2 on the new computer with the Outlook user profile name in use on the new computer. For example, if you move JohnDoe.nk2 to a new computer, and the Outlook profile name on the new computer is DoeJohn, you must rename JohnDoe.nk2 to DoeJohn.nk2 on the new computer.
You may want to save a backup copy of any existing DoeJohn.nk2 on the new computer before replacing it with the one from the old computer.
Start Outlook on the new computer. Test auto-complete. Your saved names and e-email addresses should come up as usual.
