We have added an exchange 2013 server to our existing exchange 2007 environment. We are having issues accessing OWA externally on the new server. When going to the OWA site of the new sever we are being directed to the OWA login page of the 2007 exchange not the 2013. Ports 443, 110 and 25 are forwarded to the 2013 server, but still only get the 2007 OWA. Both servers have different external OWA addresses. Any help would be appreciated, thank you in advance.
