Error Message

When someone tries to send me and e-mail from Microsoft services (365,, I do not recieve the email. And the sender gets its sent mail bounced with this error:

Reason: [{LED=450 4.4.312 DNS query failed [Message=ErrorRetry] [] [ 2023-04-19T00:13:45.822Z 08DB3F4B7F33734D]};{MSG=ErrorRetry};{};{IP=};{LRT=4/19/2023 12:12:39 AM}]. OutboundProxyTargetHostName:

It seems that microsoft can´t resolve my IP. I receive any other email from any other mail service, except for MSFT.

Does anyone has this issue? Thank you for your help.

You may want to revert to original nameserver.
Then add A record to base domain and www subdomain

As you can see in this topic, you’re not the only one having this issue:

But all we were able to establish there is that Microsoft has trouble looking up MX records on our servers. And that this issue seems to primarily affect domains.

Besides that, I have no idea. The error message from Microsoft doesn’t point to a clear issue to me, I’m not able to reproduce this issue on my own domain with my own account, and I cannot find any issues with our nameservers myself.

Hello, I had to change the server because I couldn’t solve the problem and I hadn’t been able to receive emails from Microsoft servers for almost 30 days.

tuve que cambiar de servidor, no había forma de resolver el problema rápidamente. apenas impactaron las nuevas DNS comenzaron a ingresar los emails sin problemas.


I had to change servers, there was no way to solve the problem quickly. As soon as they impacted the new DNS, they began to enter the emails without problems.
