Some mailboxes migrated from E2K to EK7 encountered error when setting the OOF. The error is "Your Out of Office settings cannot be displayed, because the server is currently unavailable. Try again later". These users dont encountered this problem when using Outlook 2003 but Outlook 2007. Have checked the below possible reasons and those settings are correct. Reason 1: Wrong Autodiscover Service settings Reason 2: Wrong certificate Reason 3: Wrong permission settings on the EWS virtual directory. Anyone have any other clue?
