I've got an Exchange Server 2007 installation that originally had SharePoint Service 3.0 (64-bit) on it, which ended up breaking OWA. I removed SharePoint, uninstalled and reinstalled CAS, which now works. However, while I still have my IIS virtual folders for OWA and Exchange ActiveSync, I'm missing the Public folder items, as well as others in IIS that used to be there before the uninstall. I don't have confidence in the installation at this point and would like to uninstall Exchange Server 2007 and reinstall it so that I have all of the folders that I should have. What is the best way to accomplish this and what might happen as a result? Are the negative repercussions to the uninstall and reinstalls?
