Applies to: Exchange Server 2016

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

Use the Set-FederationTrust cmdlet to modify an existing federation trust.

For information about the parameter sets in the Syntax section below, see Syntax.

Set-FederationTrust -Identity <FederationTrustIdParameter> -PublishFederationCertificate <SwitchParameter> <COMMON PARAMETERS>
Set-FederationTrust -Identity <FederationTrustIdParameter> [-MetadataUrl <Uri>] [-RefreshMetadata <SwitchParameter>] [-Thumbprint <String>] <COMMON PARAMETERS>
Set-FederationTrust -ApplicationUri <String> -Identity <FederationTrustIdParameter> <COMMON PARAMETERS>
COMMON PARAMETERS: [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Name <String>] [-WhatIf [<SwitchParameter>]]

This example configures the federation trust Microsoft Federation Gateway to use the certificate with the thumbprint AC00F35CBA8359953F4126E0984B5CCAFA2F4F17 as the next certificate.

Set-FederationTrust -Identity "Microsoft Federation Gateway" -Thumbprint AC00F35CBA8359953F4126E0984B5CCAFA2F4F17

This example configures the federation trust Microsoft Federation Gateway to use the next certificate as the current certificate.

Before you configure a federation trust to use the next certificate as the current certificate, you must use the Test-FederationTrust cmdlet to verify that the certificate is available on all Mailbox and Client Access servers.
Set-FederationTrust -Identity "Microsoft Federation Gateway" -PublishFederationCertificate

You can use the Set-FederationTrust cmdlet to manage the certificates used for the federation trust. You can also use the Set-FederationTrust cmdlet to refresh the metadata document from the Microsoft Federation Gateway and download its certificate.

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 ApplicationUri parameter specifies the primary domain used for the federation organization identifier.




The Identity parameter specifies the name of the federation trust being modified.




The PublishFederationCertificate switch specifies the next certificate as the current certificate for the federation trust and publishes it to the Microsoft Federation Gateway. The certificate is used to encrypt tokens with the Microsoft Federation Gateway.

Before setting the next certificate to be used as the current certificate, ensure that the certificate is deployed on all Mailbox and Client Access servers. Use the Test-FederationCertificate cmdlet to check the deployment status of the certificate.




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, dc01.contoso.com.




The MetadataUrl parameter specifies the URL where WS-FederationMetadata is published by the Microsoft Federation Gateway.




The Name parameter specifies a name for the federation trust.




The RefreshMetadata switch specifies that the metadata document and certificate is retrieved again from the Microsoft Federation Gateway.




The Thumbprint parameter specifies the thumbprint of the X.509 certificate to be configured as the next certificate for the federation trust. After the certificate is deployed on all Mailbox and Client Access servers in the Exchange organization, you can use the PublishFederationCertificate switch to configure the trust to use this certificate.




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.
