Outlook 2010 Category colors

Everyone seems to have their own color setup and majority of them will say not in master category list if you view all the colors. These were people that were upgraded from outlook 2003 to 2010. As a test I had someone create a new category and assign a color and it shows up correctly to me, and on two different outlook versions (03 and 10) however when I check someone else that had outlook 2010 installed, no upgrade from any other version the color is different and it says that it isn't in the master category list. This is confusing Ive tried to upgrade their color categories but that didnt help.

You can't have colors for categories that are not in Master Category List. Just add these colorless categories to Master Category List and you'll be able to assign them required colors.
