Check out this great post by Ben Vollmer:
Infuse your organization with new levels of customer intelligence using Microsoft Dynamics CRM version 3.0, an all-new customer relationship management (CRM) system that gives every customer-facing employee the information they need to truly impress customers. With Microsoft CRM, you can create a centralized repository of customer data that sits neatly alongside Microsoft Office and Microsoft Office Outlook -- the applications your employees probably use every day. From Outlook, employees access Microsoft CRM sales, marketing, and customer service modules to make sales decisions, market products, solve problems, and get strategic views of the business. It's CRM that works -- and works very well -- because it works the way your users already do, works the way your business already does, and works the way technology should.
