I gave this a try thankfully just after a did a True Image Backup, otherwise it would have been a disaster. Tested this twice to be sure. After install, I use Outlook 2007 with BCM and Accounting 2008 both integrated. After the Beta is installed and I open Outlook. ALL mail is now found in TASKS labeled NO DATE. Worse for my system is that on the 1st REBOOT, I can BSOD = IRQ NOT EQUAL etc. Too bad, aside from seeming a bit clunky to get into specific firewall rules etc, it seemed to perform ok. obviously a lil short to get any serious testing in.
