My company, Automation Centre, offers a Web based project management system that integrates with email systems, including Outlook. It offers tools for scheduling work, resources and CRM. As far as Outlook integration goes, you can surface it in your Outlook client, and drag-and-drop your Outlook emails to a folder to create tasks and project documents based off of them. There's a free demo if you'd like to try it out. You can learn more here: www.TrackerOffice.com .
