Errors messages in the queue viewer

Hello,

For more than a week I have error messages in the queue viewer of my Exchange server. The messages are attached as attachments.

Users report to me that emails arrive more than an hour late. Others report that they do not receive emails from their contacts.

I have looked all the settings of the Exchange servers but everything seems correct to me.

Do you know what these errors correspond to and what I need to put in place to correct these errors?
Thanks in advance !

It points to a DNS-error,
did you change something in the DNS inside or outside ?

Or another MX record

Yes, absolutely, you saw right, we are in a hybrid environment. Sorry, I didn't think to mention that.
I will read and look at the link you sent me and review all the connectors that have been created.
Thank you.

Hi Maduropa,
I don't know if there have been any changes in DNS. The DNS infrastructure is managed by the network team and they don't tell us everything... :-(
Is there a way to know what has changed in the DNS? or identify the error that indicates a wrong entry in the DNS?
Hi Dema,

The emails stuck in the queue. The mail flow is from Office 365 or Exchange On Premise?

Check the if you have a firewall configuration or some issue that is preventing from communicating with Exchange Online?

Regards
Valentina

In the end, we reviewed all our connectors (sending and receiving) and set them up so that email routing is more direct between mail servers. The tails gradually emptied until they returned to normal.
We also reviewed the connections between the sites of the countries with which we exchange.

Thank you all for your messages that helped me in solving the problem because we reviewed all these points to understand and correct these errors.

However, I have not yet fully understood the flows between AD sites. So if someone has a link.... :-)

Glad the suggestion for the connectors worked. Here is a link for AD Sites and mail flow.
