Many users use categories to organize email messages in Microsoft Outlook. We often get the request from our customers to save these (custom) categories from Microsoft Outlook 2003, so they can use them after updating to Microsoft Outlook 2007.
Microsoft does not provide a solution for this problem. That's why we developed a little application which makes it possible to import your Microsoft Outlook 2003 master categories list in Microsoft Outlook 2007.
You can download this program from the CodePlex project website.
