After upgrading to Outlook 2007 or above, you need to convert categories to color categories to add them to the master categories list.
Do this by right clicking on the top level folder (where Outlook Today is) and choose Data File Properties from the menu.
If using Outlook 2007, the command is called Properties.
It should be the last command, as seen in the screenshot, but may not be the very last item if you have add-ins installed that add commands to this menu.
In the Properties dialog, click the button to Upgrade to Color Categories. This will convert the categories and add any not already on your master color category list, to it.
If you have more than one account in your profile that uses an existing data file, you need repeat these steps for each account.
