WE have installed exchange 2010 on few customers and whenever anybody in our organization tries to open the Out Of Office assistant in Outlook 2007 or outlook 2010 (we do not have Outlook 2003 clients available) they get the following error: "Your Out of Office settings cannot be displayed, because the server is currently unavailable. Try again Later." Users are able to set the Out Of Office from OWA successfully. We have both Exchange 2010 and Exchange 2007 environments in the organization and users both environments get the same error. Both environments have their own mailbox, HT, and CAS servers with separate OWA URLs and SSL certificates. The AutoDiscover works fine and it tested ok if you go to the test conectivity and the www.testexchangeconnectivity.com site does not give any errors. I also changed the authentication settings on the EWS folder on the IIS and it does not make any difference.
