We have recently been moving some users from old PCs running Outlook 2003 to new PCs running Outlook 2010. All was fine except for the suggested contacts needed migrating, in old version this was a file called outlookprofilename.NK2 however Outlook 2010 does not use this any more.The solution is actually very simple, copy the old NK2 file from the following:For XP – C;\Documents and Settings\Username\Application Data\Microsoft\Outlook For Vista up – C:\Users\Username\AppData\Roaming\Microsoft\OutlookTo the same place on the new computer, in our case Win7 so C:\Users\Username\AppData\Roaming\Microsoft\Outlook) ensuring that filename matches the new Outlook profile.Once copied open Outlook with the /importnk2 switch to import/merge the entries to the Suggested Contacts contacts folder.
