Project Description
The Outlook Contact Category Correction Tool is designed to
correct a condition in which the categories from your Outlook
Contacts folder are removed.

To use this tool you MUST have a backup of your contacts from
a point in time where your categories were intact.

To begin you will need to create a new contacts folder in your
profile and give it a name like "Original Contacts" or
"Backup Contacts." Once you have this setup, click Next to
begin with the wizard.
