New Exchange 2003 take a running problem on the new domain, the AD/Schema/Domain were prepared for exchange 2007 before building the new domain (China domain).
Hi, Environment explanation DCGROUP.LOCAL ---US.DCGROUP.LOCAL ---UK.DCGROUP.LOCAL ---CHINA. DCGROUP.LOCAL (New domain) Note: The Exchange2003 has been installed onto the DCGROUP, US, UK domain. It means the forest & domains had been upgraded to support Exchange 2003. We did AD/Schema/Domain preparation to support Exchange2007 on March. Problem description, We built a new domain (China) under the Forest on July, it means that the China domain miss the Exchange 2007 preparation. Our plan only wants to deploy one Exchange 2003 server on the China domain. Somehow, the China\domain user accounts cant update email address through Recipient Policies and the mailboxes werent being seen under mailboxes store. Im 100% sure that the Exchange 2003 domain preparation was done before deploying, also pass exchange 2003 privilege testing over policytest utility. Regarding security groups, The Active directory of China domain is lack of permission under security table. For example, we can see the "exchange install domain servers" group under all of domain exclude China domain, and "DCGROUP\exchange recipient administrators" had been added into all domain exclude the China domain and so on. Regarding security, we dont want to add them manually in cast of missing anything. My questions, 1. While we was deploying the exchange 2003 on the new domain, whether or not the new domain need to do Exchange 2007 preparation for the China domain OR only do Exchange2003 preparation OR both of them ? 2. Is the Exchange 2007 AD/Schema of preparation compatible with Exchange 2003? I hope any who can give me a great help, if you have a similar Domain & Exchange environment on the company, even virtual environment, please.. Thanks,

The process is to do Domain preparation with Exchnage 2003 than use the Domain prep of Exchnage 2007.Since Schema is extended with Exchange 2003 first and later on you have updated with Exchange 2007 there will be no problem...
