How to do it...

To hide a mailbox from the Exchange address lists, use the Set-Mailbox command:

Set-Mailbox dave –HiddenFromAddressListsEnabled $true

How it works...

As you can see, hiding a mailbox from address lists is pretty straight forward as it requires only a simple PowerShell one-liner. The –HiddenFromAddressListsEnabled parameter accepts a Boolean value, either $true or $false. To enable this setting, set the value to $true, and to disable it, set the value to $false .

There are multiple recipient types that can be hidden from address lists. Each of the following cmdlets supports the -HiddenFromAddressListsEnabled parameter:

There's more...

Once you've hidden your recipients from the address lists, you may need to generate a report to list the objects that currently have the HiddenFromAddressListsEnabled setting enabled. Use the following command syntax to obtain this information:

Get-Mailbox -Filter {HiddenFromAddressListsEnabled -eq $true}

This searches for all mailboxes that have been hidden from address lists. It makes use of the –Filter parameter which keeps you from having to perform the filtering on the client side with the Where-Object cmdlet.
