During exam preparation I found something, that can be wrong.

I think, there is an error in the UserPrincipalName parameter. It must be aylak@fabrikam.com.

Use the Shell to create a linked mailbox

This example creates a linked mailbox for Ayla Kol in the CONTOSO Exchange resource forest. The FABRIKAM domain is in the account forest. The administrator account FABRIKAM \administrator is used to access the linked domain controller.

New-Mailbox -Name "Ayla Kol" -LinkedDomainController "DC1_FABRIKAM" -LinkedMasterAccount " FABRIKAM\aylak" -OrganizationalUnit Users -UserPrincipalName aylak@contoso.com -LinkedCredential:(Get-Credential FABRIKAM\administrator)

Hi Vladislav,

As the description mentioned , the FABRIKAM domain is in the account forest, the CONTOSO domain is a resource forest.

In this example, it will create a mailbox in CONTOSO domain, so it must be aylak@contoso.com, not @fabrikam.com.

Hi Vladislav,

Any update?

Hello!
Still very complicated to understand in which domain schould you configure what.

Today we are in Exchange 2013 but for newbie is very difficult to understand how to create LinkedMasterAccount. And there is no really clear examples. Unfortunatelly.

Would you please clarify this in examle of two domains:

source_domain.com
RESOURCE_domain.com
two-way trusts are already configured.

1.  'User1' is AD account  in 'source_domain.com'. The DomainController: 'DC01.source_domain.com'

2.  Administrator, who configure the ServiceAccount=Linked account  is  also in 'source_domain.com' : source_domain\Administrator

Does this next part of configuration schould be performed by the Administrator in 'RESOURCE_domain' ?:

3. The 'LinkedMasterAccount' must be created in 'RESOURCE_domain.com'

4. The 'Linked mailbox' should be created in 'RESOURCE_domain.com'

5. The Domain Controller: 'DC2.RESOURCE_domain.com'

6. The Mailbox Database where this Linked mailbox will be created in  is "MboxDB1" in 'RESOURCE_domain.com' on Mailbox Server 'Exch2013MB_1'.

7. The new user account in 'RESOURCE_domain' should be created in OU 'Users_Linked'

Would you please provide how the scripts now would look like with all these mentioned names?

Please help to understand?!
Regards,
Sandy
