Filter the Information

Your view still shows all the contacts in your folder. To see only the conference attendees, you need to filter the list. When you apply a filter, you see only information that meets conditions that you specify.

Click Filter (View menu) to set criteria for the filter.

Use categories to locate related items   A category is a word or phrase that you can assign any item to in Outlook. With categories, you can track items without putting them in separate folders. For example, you could assign contacts to a category called "Registrant" and then use the category as a filter criterion. Click Categories (Edit menu) to assign a category to an item. Want to see all the items in the folder again?   Click Filter (View menu), and then click Clear All.
