Import Auto-Complete List for Outlook is a lightweight solution for importing Microsoft Outlook 2003/2007 mail contacts stored in XML, DAT or NK2 files.

Users that have relied on the Microsoft mail manager throughout the years will find this tool potentially handy. Specifically, the resource can be used when switching from Outlook 2007 to 2010 or 2013, as older versions of Office suite mail manager kept the mail cache into a separate file.

This being said, one should note that the new version of Outlook allows importing contacts from older versions. Therefore, the use of this plug-in is optional.

Leaving that aside, the module integrates well with the GUI of the host software. A small frame above the Inbox stores the add-in's functions, and navigation is performed exclusively via buttons.

The tool is very easy to use. One must simply specify the location of the legacy Outlook cache files and the mail accounts to which contacts will be imported. The plug-in can read data stored in either generic XML or DAT formats, but also Outlook-specific NK2 files.

Once files are successfully imported, all the old contacts can be accessed in the newer versions of the mail manager. However, the actual usefulness of the application is debatable, as new versions of Microsoft Outlook provide users with a method of importing old contacts.

A definite plus is the fact that the plug-in runs without any need for settings adjustments. This means that no time will be wasted with tweaking the add-in.

To conclude, Import Auto-Complete List for Outlook is a simple and practical tool for importing contacts information from older versions of the mail manager to newer ones.
