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! OssianModerator June 20, 2018 at 5:02 am #192026 Have you checked the event logs? What SP and patch level are you at? What roles do the servers hold? Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
