The template automatically sends them an invitation through e-mail to join the project. When they accept, it will add a shortcut for the project to their Outlook bar so they can quickly find the project's folder. The template also creates a set of HTML pages that make it easy for people to find project information in Outlook. We've also made the Team Folder Wizard highly extensible. Developers can create their own templates and add them to the wizard and then end users can take care of the deployment.
Developers can also extend the wizard itself.
For example, developers can add customized functionality to a template, by simply adding steps to the wizard that users can walk through when they deploy a template. You mentioned new controls that are part of the Team Folder Wizard. There are two controls that developers will find very useful. One is the Outlook Team Folder Permissions control. If you've ever tried to set permissions programmatically inside of Exchange Server, you might have noticed that it's not very straightforward.
