The boss wishes to have another Authoritative email domain in Exchange 2016 of Server 2016 Essentials.
I have added Authoritative email domain, setup DNS, added new email account to bosses outlook on LAN pc works ok.
OWA works fine with new email login.
Adding exchange sync email account to mobile devices works ok.
However when setting up outlook externally on boss home pc this does not work, is there some routing thingy I need to do on Server Essentials 2016 for Outlook 2016 to work ?
