Problem

I was doing a ‘mop up’, after an Exchange install problem, (post to follow.) And went to look at the ‘Arbitration‘ mailboxes in the clients Exchange Organisation. And they could not be seen?

[box]

Get-Mailbox | -Arbitration
Get-MailboxDatabase | Get-Mailbox -Arbitration

[/box]

Solution

In my case, it was because the Exchange server was in a ‘Child Domain’ and the ‘SystemMailboxes’ are in the root domain.

You need to enter the following command first;

[box]

Set-ADServerSettings -ViewEntireForest:$true

[/box]

Then, (as shown above), re-run your commands, and the mailboxes should now be visible.
