Hey team I have an issue that has been haunting me. I got the out of office assistant to work internally for domain users. However we have a few users that are not on the domain. They use outlook on a local profile. How can I get out of office working for those users? when they attempt to access it they get a error message "server not available" When I run the autodiscovery test it fails. Do we need to purchase an additional Cert apart from our OWA cert? Is there a way to make this work?
