Most of you may remember, that in Outlook 2007 and earlier, all autocomplete email addresses were saved in the *.NK2 file, or in even older versions of Outlook they were the *.NICK file.
The NK2 file (or Nickname file) could be easily identified because it was the same name as your Outlook profile. So if you Outlook profile was called “Work Email” the NK2 file was called “Work Email.NK2”.
This made it easy to transfer that autocomplete data to a new profile.
You would create and log in with a new profile, let’s call it “Personal Email”. This would create a blank new NK2 file called “Personal Email.NK2″. Then you could simply delete that NK2 file (I usually renamed it to Personal Email.OLD” – force of habit). Next, rename “Work Email.NK2” to “Personal Email.NK2”. When you log into your new profile all your auto-complete data was there.
This all changed in Outlook 2010. [Read more…] about How To Move AutoComplete Email Addresses In Outlook 2010/Outlook 2013
