You need to be assigned permissions before you can run this cmdlet.

To see what permissions you need, see the "Transport configuration" entry in the Mail flow permissions topic.


Parameter Required Type Description




The Identity parameter specifies the identity of the Active Directory site you want to modify. You can use any value that uniquely identifies the site. For example, you can use the name, GUID or distinguished name (DN) of the Active Directory site.




The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.

  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.




The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example,




The HubSiteEnabled parameter specifies whether this site acts as a hub site. The default value is $false.




The InboundMailEnabled parameter enables or disables receiving incoming messages for all the Exchange located in the Active Directory site. Typically, this parameter is used after Active Directory site failover or maintenance.

Valid input for this parameter is $true or $false. The default value is $true. If you set the value to $false, none of the Exchange servers in the Active Directory site will be able to receive incoming messages.




This parameter is reserved for internal Microsoft use.




The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
