Use the Update-AddressList cmdlet to update the recipients that are included in the address list that you specify.


update-AddressList -Identity <AddressListIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-UseRusServer <String>] [-WhatIf [<SwitchParameter>]]


Parameter Required Type Description




Use the Identity parameter to specify the GUID, distinguished name or address list name that represents a specific address list. You can also include the path by using the format Path\AddressListName.

You can omit the parameter label Identity so that only the address list name or GUID is supplied.




The Confirm parameter causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm parameter.




This parameter specifies the domain controller to use to make the modifications to the recipients included in this address list in Active Directory.




This parameter is available only in Exchange 2007 SP2.

The UseRusServer parameter instructs the command to use the specified Mailbox server on which the Address List service is running to obtain and then set mailbox and Active Directory user attributes.

The Address List service is a component in the Exchange System Attendant service. The Address List service creates and maintains Exchange-specific attribute values in Active Directory. You can use the Address List service to update recipient objects in a domain by using specific information, such as address list membership and e-mail addresses.




The WhatIf parameter instructs the command to simulate the actions that it would take on the object. By using the WhatIf parameter, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf parameter.

The following example shows how to update the recipients of the address list named "building4" and under the container All Users\Sales.

Copy Code
Update-AddressList -Identity "All Users\Sales\building4"

Use the Get-AddressList cmdlet, piped to Format-List, to get the GUID, distinguished name, or path and name of an existing address list. Or use Get-AddressList to get a specific existing address list, and then pipe the output directly to Update-AddressList.
