Integration of Team Foundation Server work items into the Outlook user experience continues to be a popular area for innovation.  Just recently an author sent me mail about a new one called Wit-It! that enables work item forms to be easily opened from TFS work item change notifications.  It's not entirely unlike configuring links to Team System Web Access from event notifications but it uses local rich client UI that some will like better.

There are several other Outlook extension offerings out there with varying levels of completeness.  If it's an area that iterests you, you can also check out:

TeamExpand

TeamLook

TeamCompanion

And I appologize if I left any out.  As I say, clearly there is a lot of interest here and some creative people.
