Creating new Categories in Outlook 2007/2010 is not as easy as in older versions - you can't just type in the Category field. You can't copy and paste lists into the Master Category dialog. You need to select a color category from the Color Category dialog and create the categories one at a time.
How to create new color categories
- Begin by clicking on the Categorize button in any Outlook window to expand the Category list.
- Select All Categories to add new or edit existing categories or to select from categories not listed in the menu.
Click New to create a new category or select an existing category to Rename it, or change the color or keyboard shortcut.
Select (check) categories you want to apply to the selected Outlook item.
Right click on an item and choose categorize to add or remove categories.
Ctrl+click or Shift+click to select multiple items, then right click, Categorize to apply a category to the selected items.
If using By Category view, you can drag items between categories to change or remove categories.
