Hi Ankit,

Thank you very much for your reply. Can you tell me which connector log should I check?

I checked Event Viewer and found one error which seems related. See the image below.

The source IP address is the application server IP. The email relay has been working fine for a long time. I don't think there is any change on the application server. Don't know why the issue suddenly happens.

Please advise!

Thanks in advance!

Grace Yin i dont think the IP is added in the Relay of your Receive Connectors.

Go to your Exchange Admin Center (On-Premise) & Follow this Path - Mail Flow < Receive Connector , open front end - and see if the IP Address is added for your Web Server or not.

You may also verify in send connector for relay, if the IP is added or not. if it is not please add and then from Elevated CMD (On Exchange Server itself) - IISRESET FOR refresh in Web Services.

Test and see if it works 🙂

Cheers !
