continue the "advance search" feature for contacts and filter by categories
I use Outlook as my CRM for my sales job. 90% of my contacts are tagged or categorized with custom categories. I use the Advance Search feature in contacts to filter by specific category. Not having this ability is a major inconvenience and will force me to stop using Outlook to effectivelly manage my contacts database.
If you get rid of this feature, I don't know what the purpose of categories will then be?
