Use the Remove-FederatedDomain cmdlet to remove a federated domain from the federated organization identifier.

If you remove the domain used for the account namespace, federation is disabled for the Exchange organization. (The first domain specified with the organization identifier is the account namespace.) Use the Get-FederatedOrganizationIdentifier cmdlet to retrieve the domain name used for the account namespace.

For more information, see Understanding Federation.


Remove-FederatedDomain [-Identity <OrganizationIdParameter>] -DomainName <SmtpDomain> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Force <SwitchParameter>] [-WhatIf [<SwitchParameter>]]

Detailed Description

An Exchange organization's federated organization identifier is generally created using the organization's primary domain name. Additional domain names can be added and removed. The Remove-FederatedDomain cmdlet removes a federated domain from the federated organization identifier.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Federation trusts" entry in the Exchange and Shell Infrastructure Permissions topic.


Parameter Required Type Description




The DomainName parameter specifies the federated domain name to be removed from the federated organization identifier.




The Confirm switch can be used to suppress the confirmation prompt that appears by default when this cmdlet is run. To suppress the confirmation prompt, use the syntax -Confirm:$False. You must include a colon ( : ) in the syntax.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The Force parameter specifies whether to suppress warning or confirmation messages when removing a federated domain. This parameter can be used when the removal of the federated domain from Windows Live fails, but the configuration of this domain as a federated domain in Exchange should be removed regardless. The result of running this task with the Force parameter is that the Exchange configuration is removed but the domain may not be released in Windows Live. We recommend that you not use the Force parameter unless the release of the domain from Windows Live continues to fail.




This parameter is reserved for internal Microsoft use.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, 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 switch.
