I have an exchange 2010 server which I would like to fully decommission. I have recently moved all mailboxes and mail services to google apps and no longer need the exchange installation. I have already disabled all mailboxes to remove exchange from the AD users. I am at the point of deleting the arbitration mailboxes. I am having a heck of a time trying to complete this... I just want to delete them and uninstall exchange from my system. Any help is greatly appreciated!
