    Hi @navid Talesh ,

    Actually NO, you still have to run the cmdlets to prepare Schema/AD/ADdomain for the second domain, even if you are not going to install Exchange on it and only to create mailboxes for the AD users.

    Based on my test, before I run
    <ExDrive>:\Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareSchema
    <ExDrive>:\Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareAD
    <ExDrive>:\Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareDomain
    I met the same error ( domain controller wasn't found in domain) when I tried to create mailbox with a existed user in child domain.

    Regards,
    Lou
