Introduction

Are you tired of dealing with Outlook's AutoComplete feature, which can sometimes become cluttered with unwanted email addresses and names? Do you wish you had more control over the list of suggestions that appear when you type an email address or name in the message window of MS-Outlook? Look no further than NirSoft NK2Edit, a powerful tool that allows you to modify, repair, and manage the NK2 files that store this information.

Understanding NK2 Files

Every time you type an email address or name in the message window of MS-Outlook, it automatically offers you a list of users and email addresses that you can choose. This feature is known as 'AutoComplete' and Outlook automatically builds this email list according to user activity and saves it into a file with a .NK2 extension. In some circumstances, you may need to repair or modify the values that appear in the AutoComplete list, or you may want to remove unwanted email addresses and/or add new email addresses. Unfortunately, MS-Outlook doesn't provide any ability to edit this AutoComplete list, which is where NK2Edit software comes in.
