A Co-worker deleted or renamed the default site. I removed the links from the website in IIS via powershell remove-owavirtualdirectory. I then uninstalled the CAS role from the server and I am having alot of issues installing the CAS role again. At This point im going to uninstall Exchange on this server and install it on another member server. I have read to try uninstalling and reinstalling iis as well to bring back the default site but we have a couple commercial sites that can't go down for too long. I want to make sure everything that links to the old exchange server is gone. How do I correctly uninstall this properly? Just go to programs and features and click uninstall on the Exchange 2010? Also can I bring the mailboxes from the old server and if so how?
