You can supplement Microsoft Outlook’s built-in Categories field with your own Subcategory field.

Method #1 | Method #2 | Limitations | More Information

Method #1

Add a new Subcategory field to a folder like this:

1. Open a Contact.
2. Click the All fields tab
3. Select User-defined fields in folder.
4. Click New.
5. Define your new field as follows:

   Name: Subcategory
   Type: Keywords
   Format: Text

The Keywords type allows you to apply multiple subcategories to each item.

Method #2

Another method is to name your categories so they include subcategory information — for example, Business – Local, Business – Regional, Business – International, etc.

Limitations

You cannot group by more than one Keywords-type field in a view. This means that you cannot have a view that groups by Category then by Subcategory.
