The thing is that the service “Microsoft Exchange mail submission” does not start, even when it is set up as “Automatic“, in Services. Does anyone know why this could be happening?. I have restarted the server twice so far. Thanks in advance! Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
