hi!

dear on hub set in EdgeSync - first... / network/ check Use the External DNS lookup settings...
next use start-edgesynchronization
on edge goto properties of edge transport server, external dns lookups and set " use network card dns setting" on y internet-conected card, ok and done

Firstly, make sure your firewall has an exception for DNS (UDP 53) and SMTP (TCP 25)If you cannot successfully ping the smart host and receive a reponse within a few seconds, I'd suggest clearing the cache of your Internal DNS Server then restarting the DNS Server service on your DC, and restarting Microsoft Exchange Transport Service too.
That should do it.

do update

Dear All,

There is no NDR which users are recieving because emails get stuck in the queue for a long time. I do not have any edge server in my environment. i do not have any smart host in my environment. as i have said before that all other external organizations are receiving emails but not hotmail users that means their is no firewall issue as if it would then all other org would not receive emails. my problem is only with hotmail when ever my user sends email to hotmail user email stucks on the queue on hub server and queue reports erorr that dns query failed. please help

Hi All,

I have solved my problem went to the server congiuration in exchange console clicked on hub server right click and get the properties of hub server and then go to the external dns lookup and typed the external dns instead of using the first option.
