HOWTO: EWS: Disable Out-of-office / OOF message

WebDav is definitely de-emphasized and not recommended to develop applications for Exchange 2007. But WebDav was still the easiest method to disable OOF message. I was not surprised to see it NOT working against Exchange 2007 to disable the OOF message. I have a better solution for you… use my favorite technology, Exchange Web Services!!!
