When I set up an Outlook client I get this error on the new server. I have set up several servers. Currently, this Axigen Application is upgraded to the most recent version on a Windows 2016 Server. I have tried on three Outlook client and one worked and mailBird.
I did a screencast video for you of error: https://www.screencast.com/t/WsO6RwhQz It worked once on Outlook 2016 client.
hi
Your certificate does not issued to mail.pjcinvestments.com.
you need to edit ssl settings of any listeners to use the correct certificate
@Mohammad the client opened a ticket regarding this issue and we can confirm that the problem was related to the fact that the self signed certificate was still being used on the SMTPS listener on port 465.
Thank you.
