Had an Exchange 2010 install fail and after I can not get the Client Access Role to install properly. I keep on receiving an error that the OWA virtual directory is already created. I took a screen shot. I already tried editing the applicationHost file and removing the OWA lines. after I received a new error related to IIS. I ended up copying the backup of applicationHost I made. I did not want to get to deep into it. I am getting the OWA virtual directory error again. I also tried opening IIS manager and deleting the OWA virtual directory under the default website. This did not fix the error. I do not have any access to the Exchange Power Shell as the only piece that installed was the hub transport role. I need to get Exchange installed successfully so we can proceed with our migration. I included a screen shot of the error. Thank you for any help!
