Hi, I might be able to help you with this.
What you want to do is the following:1. Go to the contacts portion of Outlook.2. Select a contact then click on the categorize button then click on All Categories.
Just a quick followup - can I search contacts by Category?
You can sort by contacts - when you're at the contact screen, if you scroll to the right more you should see the category. Just click that and it should sort your contacts by categories. You can also go to the View Tab and under the arrangement part, choose categories.
