I have configured ABC.com domain in my exchange 2007 (standard edition) server and I want to configure additional XYZ.com domain in same server Kindly advice me how to configured the same With warm regards, Kiran Sawant

Hi First add a new accepted domain for XYZ.com, then create an email address policy which gives users an @XYZ.com SMTP address and finally point the MX record for XYZ.com to the same server as ABC.com - of this server is hosted by a 3rd party (like spam filtering) you will probably need to tell them too. Cheers, Steve

steve siyavaya: After followed your above steps, will I have to make changes in DC or DNS?With warm regards, Kiran Sawant

You shouldn't have to make any changes in the internal DNS - the only DNS change would be to the MX record.

In this issue, you just need to add one new accepted domain for XYZ.com and create one mx record ( for xyz.com) point to your Exchange Server. Thanks, EvanEvan Liu TechNet Community Support
