Use the Get-FederatedDomainProof cmdlet to generate a cryptographically secure string for the domain used for federated delegation in your Microsoft Exchange Server 2010 organization.

Get-FederatedDomainProof -DomainName <SmtpDomain> [-DomainController <Fqdn>] [-Thumbprint <String>]

The Get-FederatedDomainProof cmdlet generates a cryptographically secure string for the domain that will be used for federated delegation. The resulting string is used to manually configure a text (TXT) record in the Domain Name System (DNS) zone for the domain used by the administrator when running the cmdlet. A TXT record needs to be added to DNS for all accepted domains used for federated delegation. If the thumbprint of a certificate isn't provided, the task generates strings for all the certificates currently configured for the federation trust. Upon initial configuration of federated delegation, the proof string generated for the current certificate needs to be put into the TXT record for the federated domain in DNS. We recommend you update the TXT records whenever a new certificate is configured for the federation trust.

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 domain name for which the cryptographically secure string will be generated.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that retrieves data from Active Directory.




The Thumbprint parameter specifies the thumbprint of an existing certificate.

To see the input types that this cmdlet accepts, see Cmdlet Input and Output Types. If the Input Type field for a cmdlet is blank, the cmdlet doesn’t accept input data.

To see the return types, which are also known as output types, that this cmdlet accepts, see Cmdlet Input and Output Types. If the Output Type field is blank, the cmdlet doesn’t return data.

This example generates a cryptographically secure string for the domain .contoso.com.

Get-FederatedDomainProof -DomainName "contoso.com"

This example uses a specific certificate for the domain .contoso.com.

Get-FederatedDomainProof -DomainName "contoso.com" -Thumbprint AC00F35CBA8359953F4126E0984B5CCAFA2F4F17.
