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:
- Open a Contact.
- Click the All fields tab
- Select User-defined fields in folder.
- Click New.
- 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.
More Information
- See Microsoft Outlook Categories for a list of addins for working with categories.
