Consider the following scenario in a Microsoft Exchange Server 2016 environment:
- You have multiple domains (parent and child domains) in an Active Directory forest. An Exchange server is installed in one of those domains and users are located in a sibling domain of the domain where the Exchange server is installed.
- You notice that the RecipientViewRoot parameter in the Get-ADServerSettings cmdlet is set to the domain where the Exchange server is installed by default. This means that when you run the Get-Mailbox cmdlet, it will return mailboxes that are in that domain only.
- You change the recipient scope to sibling domains by using the RecipientViewRoot parameter.
- You run the Get-Mailbox cmdlet and expect to see the mailboxes of the sibling domains.
Unexpectedly, you see the mailboxes still from the domain where the Exchange server is installed.
