How to move a user's list of Autocomplete eMail in Outlook

In order to migrate a user's Autocomplete settings a file, commonly reffered to as a NK2 file must be transferred to the new Outlook profile (on a new computer or on the same computer).
After Outlook is setup on the machine and the user sends their first eMail to confirm Outlook is otherwise working, overwrite the current NK2 file with the file from the elder profile.
 
The location of the NK2 AutoCompelete file created by Outlook might be different from one computer to another, depending on the operating system and the version of Outlook. 
Here's the rules for finding the location of your NK2 file:
  • For Outlook 2003/2007 with Windows 2000, Windows XP, or Windows Server 2003: 
    The location of the nk2 file is C:\Documents and Settings\[User Profile]\Application Data\Microsoft\Outlook 
    The name of the NK2 file is identical to the Outlook profile name, with .nk2 extension.

     

  • For Outlook 2003/2007 with Windows Vista or Newer: 
    The location of the nk2 file is C:\Users\[User Profile]\AppData\Roaming\Microsoft\Outlook 
    The name of the NK2 file is identical to the Outlook profile name, with .nk2 extension.

     

  • For Outlook 2010/2013 with Windows Vista or Newer: 
    The nk2 file is located in C:\Users\[User Profile]\AppData\Local\Microsoft\Outlook\RoamCache 
    The name of the NK2 file is in the following format: Stream_Autocomplete_X_AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA.dat The X is the file index (usually 0) and AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA is a random 16-byte key in hexadecimal format.

     

  • For Outlook 2010/2013 with Windows XP: 
    The nk2 file is located in C:\Documents and Settings\[User Profile]\Local Settings\Application Data\Microsoft\Outlook\RoamCache 
    The name of the NK2 file is in the following format: Stream_Autocomplete_X_AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA.dat The X is the file index (usually 0) and AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA is a random 16-byte key in hexadecimal format.
Additionally a trial version of NK2Edit can be used to facilitate changes: http://www.nirsoft.net/utils/outlook_nk2_edit.html
