Outlook Integration

I (like so many others) use Microsoft Outlook for my email, contacts, calendar and task management. Outlook is the killer application for my desktop. As I evaluate productivity applications (CRM, Sales and Marketing, Service Management, etc…) I am constantly looking for the deep integration with Outlook. Why is this important? Outlook provides a conduit for me to communicate with the outside world, organize and track my contacts, schedule and tasks. I use Outlook to sync to and from my Blackberry and my billing system. To put it simply, when my computer is running Outlook is running and I keep tabs on it.
There are some fantastic CRM and Service Management tools available today. While the open source community has some great applications, and there are some wonderful (relatively) inexpensive commercial applications, I have yet to find a tool which allows for the seamless two way communication that I need. Why is this important? Having the same or similar data in multiple places (Email, CRM, Accounting) to some degree is a fact of life with the SMB application suites. Being able to effectively view, understand, and act on this information is critical. The more information that you can evaluate in a shorter amount of time, the more effective you become.
More importantly, I’m fundamentally lazy. I want software and systems to make my life easier, so give me deep integration with Outlook.
