How to backup and restore “Cached Emails Addresses” from Outlook
This had taken me forever to find a good answer for. Up until now that is. 
I had known that if you used Microsoft’s built in User and Settings backup wizard that these items would be backed up. Unfortunately because we run such a tight ship on our clients networks it takes very little to get them backup and running when we swap out machines. The time it takes to backup a user’s setting using the “User and Settings Backup wizard” did justify using it.
You might ask why is this such a big deal? The reason why it is such a big deal is people have come to expect that when you use programs like Hotmail or Gmail the auto-complete of the emails is available anytime and anywhere. Users are getting used to rely on this instead of actually creating contacts the traditional way. I tend to find Admin staff are REALLY bad for not creating a contact for people that they talk to on a regular basis especially if they only talk to them really through email (They are better about creating contacts if they have to talk to them over the phone etc).
This “how to” shows you how to copy the email addresses they have typed over the life of their computer.
*NOTE* – Previous Outlook programs you will need to find the .nck or .nick file
*NOTE* – Outlook 2003/2007 the file you will need is .nk2
How to backup the Cached Email addresses from Outlook
The file you are going to need is located in your profile directory.
- Windows Vista/7 – C:\Users\<user>\Application Data\microsoft\Outlook
- < Windows Vista – C:\Documents & Settings\<user>\Application Data\microsoft\Outlook
*NOTE* If you can’t find the file it might also be here C:\Users\<user>\AppData\Roaming\Microsoft\Outlook
Copy this file and back it up to another location like a flash drive.
I was also told about a program called “NCKCSV”. This program allows you to backup your “quick outlook contacts” and save them as a CSV file. Once you have done that you can import them into your contacts in outlook.
How to restore the cached email addresses from Outlook.
Basically all you have to do is reverse the backup process.
- Make sure that you have created the profile for the person both on the computer as well as in Outlook.
- Copy the file from the flash drive back to the user profile directory for Outlook.

You first want to download the program called: NCK2CSV
Run the app.
Click “Browse” button. Search for the file location I listed above.
Select where you want to save the file to and hit “Export Now”. The program will export the email addresses to a contact list.
From the horse’s mouth
I got these tweets directly from a Microsoft employee for whom I am very thankful had seen my original question to a fellow Winnipeg IT professional and answered my question.
