>> Cleaning Outdated Email from AutoComplete (.nk2 file)
Feb 2003

AutoComplete (of email address) is a convenient feature of Outlook XP, 2003 and 2007 but it may not always read your mind right. It can get confusing when a coorespondent of yours recently changed email address and although his/her new nickname remains the same or similar to the old one, the underlying email addresses are different. It is especially sticky if you have two coorespondents with similar nicknames and Outlook may try to autofill with the wrong person. With a little oversight and fast fingers, you may accidently send an office joke to the wrong Joe or hand your confidential report to someone else on a silver platter.

I just had a small mishap of the first scenario where the recipient has changed her address. It was changed half a year ago but there has not been an incident communicating with her until today when I composed a new email. With Outlook AutoComplete's good memory, it sure remembered the past and filled in the old address when I started typing in her first name. Gullible as I was, I used it without double checking and merrily sent the email out before the noon deadline. Lightning struck when I came back an hour later with a returned mail from the dreaded Mail Delivery Subsystem, and it hit me that I had sent to an outdated address. This incident reminded me that I should clean up some of the outdated addresses still being remembered by Outlook XP's AutoComplete.

There are two ways you can go about it, you can "delete as you go", or simply "start over".

To Delete as You Go

Type the nickname in the To: field as you normally would. When Outlook finds a match for it, a small box would show up where you can scroll with your keyboard up/down keys to select the address you want. Highlight the name(s) you want to delete and press DELETE on the keyboard. The next time the box comes up again, you'll see the unwanted name(s) gone.

Simply Start Over

To reset the nickname file and start fresh, you can delete the current .nk2 file or rename it to something else as a backup (always a better idea!). Outlook will rebuild one at the next restart.

If you are running 2000/XP, you'll find this file in C:\Documents and Settings\<your username>\Application Data\Microsoft\Outlook in the name of <profile name>.nk2 unless you've installed your OS onto a different drive. <profile name> is what you name your Outlook profile, the default name is "Outlook".

If you're running NT, try looking into C:\Winnt\Profiles\<username>\Application Data or C:\Winnt\Profiles\<username>\Local Settings\Application Data e.g. I only have one profile and is just called Outlook so I will use Outlook.nk2 for AutoComplete

** If you are performing a search for the .nk2 file and nothing turns out from the search, or not able to go into the directory and locate these files, please note that these are, by default, hidden files in Windows. You're blind folded from them until you decide that you're ready to handle them. To enable, just open up Windows Explorer, under Tools | Folder Options | the View tab and select "Show hidden files and folders". For me, I also like to uncheck "Hide extensions for known file types" and "Hide protected operating system files".

While you're there, you may notice other files of interest. Let's take a look at them while we're in the neighborhood -- (not all versions of Outlook use the same files, you may find that you don't have some of the files mentioned here)

.fav -- which as the extension suggests, is your Favorites file that contains the settings for the Outlook bar as well.

.srs -- is the file that keeps your send/receive group settings for those who use Outlook for multiple email accounts.

.rwz -- is where pre Outlook XP versions keep your mail filtering rules.

There are also other files that are not based on your profile name --

Junk Senders.txt -- is a plain text file full of email addresses of, namely, junk senders that you have identified and put into blocking mode within Outlook XP.

Outcmd.dat -- keeps your customized toolbar settings

OutlPrnt (no extension) -- keeps your customized print settings.

Other files that may be more familiar to you are --

.pst -- your personal folder which you may choose to save at a different location.

.pab -- your personal address book.
