Hi,
We recently introduced a Exchange 2010 server into our Exchange 2003 enviroment but had to stop migrating users over to it after it became appartent that users using Outlook 2010 could not switch on their Out Of Office, getting an "Your automatic reply settings cannot be displayed because the server is currently unavailable" error. However users on the new 2010 can set OOF if they use OWA or Outlook 2003!
Running the Test E-mail AutoConfiguration shows no errors with the Log tab showing Autodiscover succeeded and the Results tab showing all the correct values, including a OOF URL of /Autodiscover/Autodiscover.xml">https://<servername>/Autodiscover/Autodiscover.xml into IE gives a XML file with a 600 error code.
I have looked at loads of 'solutions' on the Internet but cannot get this working, anyone have any suggestions?
Thank you,
Craig
