Tearing Down Exchange

I'm having a lot of fun this week tearing down an Exchange envrionment. I just deleted some three thousand mailboxes. Poof. All gone. Bye bye. More challenging is ripping out the public folder stores. Those things just don't want to die. I knew about deleting the OWA scratchpad and Store Event system folders, but it still wouldn't die. I finally went out on a limb and deleted the Schema system folder. Then it deleted easily. Hope that folder wasn't too important. But I figure we're shutting this whole domain down shortly anyway so how much impact could I really have. Deleting is so much fun! :-)
