error sending to an email address
Posted on 2012-04-05
I have a user trying to send to an email address and we are getting NDRs. The email address appears to be good. We can receive from the email address, but replying or sending a new email to the address doesn't work.
We are using Outlook 2010 connecting to Exchange 2003.
We have also tried sending via OWA with no success.
I was able to successfully send to the email address from my personal hotmail account.
The NDR is below.
