On-premise are not receiving email
We are running Hybird environment and since few days on-premise users are not receiving email or would receive late like after hour or so. I sent one email from office 365 user to on-premise user...
Yes we did setup through HCW.
When messages sent it shows pending in message trace and give the below
It would be send if failed then would get a below error: original domain name has been replaced with abc.
Reason: [{LED=554 5.4.14 Hop count exceeded - possible mail loop ATTR34 [QB1CAN01FT015.eop-CAN01.prod.protection.outlook.com]};{MSG=};{FQDN=abc-ca.mail.protection.outlook.com};{IP=104.47.60.36};{LRT=2/29/2020 5:16:28 AM}]. OutboundProxyTargetIP: 104.47.60.36. OutboundProxyTargetHostName: abc-ca.mail.protection.outlook.com
In O365 outbound connector i have included on-premise exchange FQDN and our default domain.
Should we removed default domain?
Thanks,
Hello Yousuf khan,
I hope you validated the connector successfully. Just issue might be with Looping the mail from o365 to On-premises. Check with your Default Accepted Domain and keep domain type as Relay. Hope this will solve your problem.
