In Outlook, there are no standard tools for restoring backups of Auto-Complete Lists, and even worse, there is no way to load Auto-Complete Lists from external files. This utility imports the Auto-Complete Lists in NK2 or XML file format into Outlook 2010 and above. Because, in the latest versions of Outlook, Auto-Complete Lists are stored directly in the user's mailbox (or PST data files), each account has its own Auto-Complete List. To transfer the Auto-Complete List from Outlook 2007 (and below) to the newer version of Outlook, you need to select NK2 file and specify the target data file or mailbox. To work correctly, always import the Auto-Complete Lists with Outlook closed, otherwise after closing Outlook, imported data may disappear. Import of Auto-Complete List is possible in three modes. In the mode of adding new elements, the utility imports only elements that do not exist in the Outlook Auto-Complete List. To ensure uniqueness, it compares e-mail addresses and all duplicates are ignored. In this mode, you can safely import several files one by one; only the unique addresses will be added. In update mode, the utility adds new contacts and refreshes existing data, such as a user name or Exchange Server address. In replace mode, the existing Auto-Complete List will be replaced with the imported data.
