Hello everyone,
I have an Hybrid Exchange 2013 environment with Edge Server and an Antispam.
I will change my Antispam and I change the smarthost in Edge pointing to the new antispam´s IP I notice the following error on emails stuck on queue:
“The error was: 421 4.4.2 Connection dropped due to SocketError." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. The last endpoint attempted was 104.47.59.138:25};{FQDN=mydomain.mail.protection.outlook.com};{IP=104.47.59.138}]”.
I need a help for this question:
since I have an Edge Server, I have to change the smarthost pointing to the new Antispam´s IP, remove the subscription, create a new subscription, then run the HCW (Hybrid Configuration Wizard)? Do I have not to change the Receive Connector, only the Send Connector, is that right?
As per I know, we cannot use a public certificate in Edge server so I do not change the self-signed certificate used in connector, right?
If anyone can help me, I appreciate.
Thank you.
Best Regards.
