I am running a coexisting environment with Exchange 2007 and 2003. Almost all mailboxes have been transferred to the 2007 box, but my free/busy and auto configure services are not working. All I receive in the scheduling assistant is a gray bar that never populates. When trying to set up the Out of Office all that is received is ...server is unavailable. When I test auto configuration I revieve an error contactingthe internal url (0x800C8203), and when i run test-outlookwebservices | fl, I get a 500 error : the email address cannot be found. All clients are using Outlook 2007. The public system folders have been replicated from the old server to the new server and the internal urls for the CAS, Autodiscover, EWS have been double checked and are correct. I have applied a verisign cert to the server and OWA is fully functional with no flaws. I have two Macs on the network and they are able to utilize all functionality of the new server using OWA as an access point. Authtentication for both the EWS and Autodiscover are set for Windows Integration and Basic. I have read several of the posts on EE and cannot find a solution. Any assistance would be greatly appreciated, this was supposed to be a great addition for the security of email communication and overall functionality.
