My company owns a domain - company.com and a web site. This site is at our hosting provider. I've set up Active Directory - a subdomain of company.com - corp.company.com (I did not want to use .local domain or set up split zones and I could not move site to my server because of slow internet speed). I made an A record in cPanel pointing to public ip of my workplace. Now the problem is when I install Exchange server and import users they look like this: user@corp.company.com This is not what we want. We want to have mail accounts with root domain name (without "corp") like: user@company.com and of course send and receive mails from outside. I'm not sure but I think it is possible. What configuration should I have for this? What MX record should be in cPanel?

Hi, The e-mail address added to the mailboxes are set by the e-mail address policiy created on the exchange server. Just remove the corp. from this and it should work. On the internet you need two DNS records - one A record with the external IP address of your network and one MX rocord pointing the the A record. Leif

Hi Agree with Leif You can add the smtp domain into accepted domains and setup email address policy, then give user mailbox with a proper configured email address.
