We have one exchange server 2003 and the default domain is www.arh.ae
it is working fine. Then we acquired another domain which is www.abads.ae
and I added the second smtp address as @adacs.ae in recipient policies and it updated the address in the users.
But we cannot login using the new email address email@example.com in OWA or even using pop3.
I have made this email address primary.
Both the MX Records are already updated.
