• Windows XP: Start -> Run -> “%userprofile%\Application Data\Microsoft\Outlook”
• Windows 7: Start -> Run -> “%appdata%\Microsoft\Outlook”

Import Outlook nicknames from .NK2 file to Outlook 2010 Profile

1. Copy *.NK2 to %appdata%\Microsoft\Outlook
2. Change name of .NK2 file to match the Outlook profile name (This can be checked using “Mail” in control panel)
3. Start -> Run -> “outlook.exe /importnk2” (This imports the NK2 file into the profile)
4. Once imported the .nk2 file should get renamed automatically with . file extension
5. Import of Contacts will merge with current cache (not overwrite)
