Whenever a Microsoft Outlook user fills in an email address in the email client it will be saved by the software so that it can be auto completed the next time part of the address is entered in the to, cc or bcc field in the client.
NK2View is a Nirsoft application that can be used to manage those stored auto complete entries in Microsoft Outlook. The software program is fully portable and should run on most versions and editions of Microsoft Windows. The name of the software is directly related to the file extension of the auto complete entries. Outlook stores them in .n2k files that are named after the profile name.
It displays the auto complete entries of the default Outlook profile by default with an option to load the auto complete entries of other profiles as well. Once loaded the software program lists information such as the email address, display name, the auto complete value or the type.
The auto complete entries can be edited and deleted which is useful for removing obsolete or incorrect entries from the auto complete file.
Users with multiple computers will like the option to export the entries into xml, html or txt format. The software program for Microsoft Outlook does come with another interesting option. It can be used to add information from the Microsoft Outlook address book to the auto complete entries.
Users should be aware that the auto complete limit is 1000 entries. They should backup the .n2k files before they make any changes to the files to avoid corruption or other issues that are unlikely to arise but may still happen due to unforeseen events like a crash.
Nirsoft has released NK2Edit in 2010 which is an improved version of the original tool to edit the auto complete values of Outlook. It supports a variety of additional features, including options to copy values from one file to another, extracting data from corrupt nk2 files, and command line support.
