I have successfully used the CSS to load-balance an application in our network for some time. I have just added to the configuration to allow load-balance of new Microsoft Exchange Servers. It appears that the load-balancing works for Microsoft Outlook users but "not" for Microsoft OWA users. It appears that Microsoft OWA users cannot get to the site when the rules are active. We cannot find in Cisco docs what we are missing. I have included my configuration below. Any help is really appreciated. Thanks. Lisa
