Any Logs? is this an active//active dag with DAC? I had this issue the other day with a corrupted database and had to rebuilt it which cause mail to stop routing. Check to make sure edge transport is also working correctly.

Stop and restart the Transport Service to see if that gets things moving.

If it doesn't, the next question is "What recently changed?".

Something has to have changed.   A working Exchange server does not simply stop sending emails.

Are you able to receive emails?

Is your Cert still valid?

SMTP relay?  Check for any blacklisting.

the issue was at the ISP end. not sure what was the issue as internet was working for everyone in the office even on these two servers but still the mails were not going out.

however when the issue was reported to ISP and then after an hour it started working.

I presume the issue to be with DNS forwarding.

Thanks for all the support

the issue is beyond the local issue it was at the ISP end
