Import NK2 file into Outlook 2010

06 Sep

I just found today that Microsoft Outlook now store the old NK2 data on Exchange 2010.  So now outlook keeps a cache file structor instead of the out NK2 file.

  1. Place the existing .NK2 file into %appdata%\Microsoft\Outlook.
  2. a) If you have openned outlook already there should be some files in there already make sure your .NK2 is named the same.
    b) If you haven’t opened outlook the file need to be named the same as your outlook profile. This can be checked by

    • Press Start button and in the search field type Mail click the top result under Control Panel, Microsoft Outlook Profiles
    • Click the Profiles button
    • Ensure the NK2 file is the same as in that box
  3. Hold the Windows button on your keyboard and press R
  4. In that box type outlook.exe /importnk2 and click OK

This will import your contacts, if your keeping an eye on what’s going on, the .NK2 will stay present until outlook is closed where it will then be renamed as .NK2.OLD.

Funny, the reason I needed to research this is for some reason, outlook failed to do it the first time.  It renamed it to .NK2.OLD but the to contacts were not working.  Luckily is was a case to undo the rename, and run the command again.
