PDF preview handler for Outlook 2007 and/or Windows Vista

I am surprised that Adobe didn't create this themselves but they seem pretty anti-Microsoft lately anyway.
Check it out here.

It needs Adobe Reader 7.x or higher installed for the API calls, so that is noteworthy for FoxIt users.
It also needs .Net 2.0 Framework, but 99% of the users running Office 2007 and/or Vista will have that installed already.
