Using Outlook/Exchange Server as a central dispatch manager?

[Ted Clouser]

I'll try to be detailed, but brief. Running Exchange 2K with mixed Outlook clients throughout office. We're a service company and we have a mailbox called "dispatch". When a service call comes in, we create a new task in the Dispatch mailbox, add the detail and then "assign" it to someone. They accept and update until the call is complete (every time a change is made it synchs with dispatch's task). When the call is complete/closed, the task in central dispatch is closed and then processed

We want to enhance some of this -- are there any features in Exchange 2003 that would help or are we just stuck looking at a third party mgmt software that can't integrate with Outlook?
