2,116Hi,
I'm trying to configure an On Premises SMTP email server inside D365 CRM Online to send emails. I have also added the range of IP addresses provided by MS on email server so that these are not blocked. But even after doing all that I keep on receiving below error when i test the email server configuration.
Email Server Error Code: UnknownOutgoingEmailIntegrationError
ActivityId: 6db640a1-9ee9-4a72-8159-eca13177a052
>Error : System.IO.IOException: The operation is not allowed on non-connected sockets.

Not sure if i'm missing any configuration or any changes are required on EMail server.
Thank You!
