We are getting an out of office error: "Microsoft Office Outlook... Your Out of Office settings cannot be displayed, because the server is currently unavailable. Try again later." But If we log in to OWA we can set the Out Of Office. I've read about the auto discovery and we have confirmed it's set up. One of my co-workers remembers once before that we had to start a service. I've went through the required and optional services listed for Exchange 2007 and have them setup correctly. I've compared our services with another Exchange 2007 environment and most are the same so I set it up the same then put them back.Thank you for your time and help....

All, It looks like the issue is resolved now, we installed the service pack and the issue has been resolved. Our time frame for deploying patches sometimes lag and for some reason our lead Adminstrator had not applied it yet.Thank you for your help!Dennis
