Hello, You can host more than one domain on your Exchange server. The easy way steps are: 1. Add the domain to the Exchange server's SMTP Domains 2. Change DNS zone and an MX record in the authorative server's DNS, wait for propagation (clear your ws cache IPCONFIG /FLUSHDNS) 3. Select the default domain for each user in AD See this article for more details Cheers Miguel Fra / Falcon IT Services Computer & Network Support, Miami, FL Visit our Knowledgebase and Support Sharepoint Site
