Here is our current configuration,
1 2013 exchange server
1 domain which was the original domain setup in exchange can send and receive email
The second domain which was added to the following settings can not send or received. An MX lookup shows the domain is pointed to the right IP
Domain Added to accepted domain ( New domain set as default )
default policy edited with new domain ( @domain.com added to default policy)
users email account profile shows both domains
Any ideas, this is a first for us.
