Hello Dear Friends how are you.? i am planning to host multiple domains on single exchange server 2007 with sp1, mydomain.com & mydomain2.com. i want to create a policy on OU that if user is in OU1 then it will automatically be associated to mydomain.com & if user is in OU2 then it will be automatically associated to mydomain2.com.& can i publish OWA, outlook anywhere & activesync of both domains (6 services) through single IP.? my Exchange 2007 SP1 is installed on Windows 2008 Enterprise Server. kindly tell me how can i accomplish this task.? your positive replies will be highly appriciated.

Dear Mates, i have resolved the issue through email policys but kindly tell me how can i accociate new Recieve connector to mydomain2.com.? as it conflicts with recieve connector of mydomain.com because the IP is same. & how will i publish these two domains over the Internet in form of OWA, ActiveSync & Outlook Anywhere.? kindly tell me the appropriate solution.

Basically, Exchange 2007 has the same way for hosting domain like Exchange 2003, you can complete it like Exchange 2003 general steps. Please refer to below link(steps for Exchange 2003) http://www.msexchange.org/tutorials/Shared_Hosting_Exchange_2003_Part1.html Meanwhile, it seems that you are not necessary to create additional receive connector. Please refer to your another thread. http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=3496794&SiteID=17 hope the post helps for other folks in the future. Jason
