Applies to: Exchange Server 2016

This cmdlet is available only in on-premises Exchange Server 2016.

Use the Remove-FederatedDomain cmdlet to remove a federated domain from the federated organization identifier in the federation trust for the Exchange organization.

If you remove a domain configured for federated sharing, federated sharing for that domain is disabled.

For more information, see Federation.

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

This example removes the federated domain from the federated organization identifier.

Remove-FederatedDomain -DomainName

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 infrastructure and PowerShell 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 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 Force switch 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 switch 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 switch unless the release of the domain from Windows Live continues to fail.




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.
