Hello! In our company we have tow domains that have full trusts between them. Let's name the two domains "domain1" and "domain2" for simplicity. Many time ago someone installed exchange server 2007 in "domain1", but all the users that are using exchange are in "domain2". Can I tranfer the configuration domain controller form "domain1" to "domain2" and remove "domain1" afterwords?

If thats only a resource account forest , its not possible Read the Arcticle below - http://blogs.technet.com/b/exchange/archive/2006/11/02/3396084.aspx Search for Exchange 2007 Resource Forest Migration , Satheshwaran Manoharan | Exchange 2003/2007/2010 | Blog:http://www.careexchange.in | Please mark it as an answer if it really helps you

Hi 1. You can use admt. You can move user from domain2 to domain1. 2. You can install exchange 2007 in domain2. 3. You can create linked mailbox in domain1. http://technet.microsoft.com/en-us/library/bb123524(v=exchg.80).aspx example: New-Mailbox -Database "Mailbox Database 1" -Name "John Peoples" -LinkedDomainController "DC01fabrikam" -LinkedMasterAccount fabrikam\john -OrganizationalUnit Users -UserPrincipalName john@contoso.com -LinkedCredential:(Get-Credential fabrikam\Admin01) But you can't remove domain1 dc.

Can I tranfer the configuration domain controller form "domain1" to "domain2" and remove "domain1" afterwords? Hi, Yes you can change the ConfigurationDomainController if you want to, but it shouldn't be necessary to do so. Example: $AdminSessionADSettings.ConfigurationDomainController = 'DC.domain2.com' Martina Miskovic

Hi If there aren't any users or mailboxes in domain1, you can remove exchange 2007 and AD. http://technet.microsoft.com/en-us/library/bb123893(v=exchg.80).aspx It won't affect domain2.Terence Yu TechNet Community Support
