I have a new user in my organization.
He owns his own domain name (hisdomain.com)and uses email email@example.com)
Previous organization have set up their exchange 2003 so emails were arriving in their exchange.
I did dnsreport on his domain and found out the MX record on hisdomain was pointing to his previous employer. I can easly organize so MX record on hisdomain will be pointing to my exchange but i dont really know what i have to do on my exchange after that.
At the moment he is still using previous organization email services and checking his email over OWA. I dont want redirect MX record just yet as he will be left with no email as i dont know what do i have to do on my exchange.
Can anyone help me with this issue.
