Did you run setup/PrepareAllDomains when you installed Exchange?
Do you have missing DCs?

What does Event 2080 show on the Exchange Server in that second domain?

Hi @navid Talesh ，

Agree with Andy, you could try /PrepareAllDomains to prepare the second domain for the using of Exchange server.

Hi Andy

I already have an exchange in my organization and now another domain has been added to my Forrest.
The question is that preparing the domain for installing the exchange must be done before installation. Can I still do this after installing the exchange ??

Answer 1

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.

Hi @navid Talesh ,

The second domain, have you deployed a DC for it? And then run the PrepareSchema/AD/Domain cmdlets as above?

Basically this error message referred to a Connection error between the Exchange AD topology service and the domain controller. I think you could verify if Active Directory replication is working as expected.
