Applies to: Exchange Server 2016

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

Use the Set-AuthServer cmdlet to configure an authorization server that partner applications can use to obtain tokens recognized by Microsoft Exchange.

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

Set-AuthServer [-AuthMetadataUrl <String>] [-TrustAnySSLCertificate <SwitchParameter>] <COMMON PARAMETERS>

Set-AuthServer [-AuthMetadataUrl <String>] [-IsDefaultAuthorizationEndpoint <$true | $false>] [-TrustAnySSLCertificate <SwitchParameter>] <COMMON PARAMETERS>

Set-AuthServer [-RefreshAuthMetadata <SwitchParameter>] <COMMON PARAMETERS>

COMMON PARAMETERS: -Identity <AuthServerIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Enabled <$true | $false>] [-Name <String>] [-WhatIf [<SwitchParameter>]]

This command disables the authorization server ACS.

Set-AuthServer ACS -Enabled $false

Partner applications authorized by Exchange can access their resources after they're authenticated using server-to-server authentication. A partner application can authenticate by using self-issued tokens trusted by Exchange or by using an authorization server trusted by Exchange. You can use the New-AuthServer cmdlet to create a trusted authorization server object in Exchange, which allows it to trust tokens issued by the authorization server.

Use the Set-AuthServer cmdlet to enable or disable the authorization server, change the AuthMetadataUrl parameter, or refresh authorization metadata.

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 "Partner applications - configure" entry in the Sharing and collaboration permissions topic.


Parameter Required Type Description




The Identity parameter specifies the identity of authorization server.




The AuthMetadataUrl parameter specifies the URL of the authorization server. This can be the AuthMetadataUrl of your Exchange Online organization.




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 Enabled parameter specifies whether the authorization server is enabled. Only enabled authorization servers can issue and accept tokens. Disabling the authorization server prevents any partner applications configured to use the authorization server from getting a token.




The IsDefaultAuthorizationEndpoint parameter specifies whether this server is the default authorization endpoint. This server's authorization URL is advertised to calling partner applications, and applications need to get their OAuth access tokens from this authorization server.

Valid input for this parameter is $true or $false. The default value is $false.




The Name parameter specifies a name for the authorization server.




The RefreshAuthMetadata switch specifies whether Exchange should refresh the auth metadata from the specified URL.




The TrustAnySSLCertificate switch specifies whether Exchange should accept certificates from an untrusted certification authority. We don't recommend using this switch in a production environment.




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.
