Hello, I have an Exchange Server 2010 RTM with SP1 installed. If I open the EMC and go to Tools and double-click the RBAC utility, it opens IE8 but says the website cannot be displayed. I believe this is some sort of issue with IIS, but I can't see anything that looks wrong. I can open OWA and then access "Manage My Organization", but only if I go directly to OWA and sign in. I can also access RBAC via EMS. Thanks in advance for your help!
