Nope!! There have been a few threads on here about getting it to work. I'm running RC1 build 5600 and have not been able to get 4.1 or 4.2 working. There are also issues with Desktop Manager working with Outlook 2007 on XP machines. I'm constantly keeping my ear to the ground on this one but as of yet there's nothing I've heard. If I do get something I'll be sure to let you know!
