Description

Although it's possible to create a Windows PowerShell virtual directory, we recommend that you only do so at the request of Microsoft Customer Service and Support.

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

Examples

Example 1

New-PowerShellVirtualDirectory -Name "Contoso Certificates Required" -BasicAuthentication $false -WindowsAuthentication $false -CertificateAuthentication $true

This example creates a Windows PowerShell virtual directory and configures it to accept only certificate authentication.

Parameters

-BasicAuthentication

The BasicAuthentication parameter specifies whether Basic authentication is enabled on the PowerShell virtual directory. The valid values are $true and $false. The default value is $true.

Type:Boolean
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-Confirm

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.
Type:SwitchParameter
Aliases:cf
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-DomainController

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.

Type:Fqdn
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ExtendedProtectionFlags

The ExtendedProtectionFlags parameter specifies custom settings for Extended Protection for Authentication on the virtual directory. Valid values are:

  • None: This is the default setting.
  • AllowDotlessSPN: Required if you want to use Service Principal Name (SPN) values that don't contain FQDNs (for example, HTTP/ContosoMail instead of HTTP/mail.contoso.com). You specify SPNs with the ExtendedProtectionSPNList parameter. This setting makes Extended Protection for Authentication less secure because dotless certificates aren't unique, so it isn't possible to ensure that the client-to-proxy connection was established over a secure channel.
  • NoServiceNameCheck: The SPN list isn't checked to validate a channel binding token. This setting makes Extended Protection for Authentication less secure. We generally don't recommend this setting.
  • Proxy: A proxy server is responsible for terminating the SSL channel. To use this setting, you need to register an SPN by using the ExtendedProtectionSPNList parameter.
  • ProxyCoHosting: HTTP and HTTPS traffic may be accessing the virtual directory, and a proxy server is located between at least some of the clients and the Client Access services on the Exchange server.
Type:MultiValuedProperty
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ExtendedProtectionSPNList

The ExtendedProtectionSPNList parameter specifies a list of valid Service Principal Names (SPNs) if you're using Extended Protection for Authentication on the virtual directory. Valid values are:

  • $null: This is the default value.
  • Single SPN or comma delimited list of valid SPNs: The SPN value format is Protocol\FQDN. For example, HTTP/mail.contoso.com. To add an SPN that's not an FQDN (for example, HTTP/ContosoMail), you also need to use the AllowDotlessSPN value for the ExtendedProtectionFlags parameter.
Type:MultiValuedProperty
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ExtendedProtectionTokenChecking

The ExtendedProtectionTokenChecking parameter defines how you want to use Extended Protection for Authentication on the virtual directory. Extended Protection for Authentication isn't enabled by default. Valid values are:

  • None: Extended Protection for Authentication isn't be used on the virtual directory. This is the default value.
  • Allow: Extended Protection for Authentication is used for connections between clients and the virtual directory if both the client and server support it. Connections that don't support Extended Protection for Authentication will work, but may not be as secure as connections that use Extended Protection for Authentication.
  • Require: Extended Protection for Authentication is used for all connections between clients and the virtual directory. If either the client or server doesn't support it, the connection will fail. If you use this value, you also need to set an SPN value for the ExtendedProtectionSPNList parameter.

Note: If you use the value Allow or Require, and you have a proxy server between the client and the Client Access services on the Mailbox server that's configured to terminate the client-to-proxy SSL channel, you also need to configure one or more Service Principal Names (SPNs) by using the ExtendedProtectionSPNList parameter.

Type:ExtendedProtectionTokenCheckingMode
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2016, Exchange Server 2019

-ExternalUrl

The ExternalUrl parameter specifies the external URL that the PowerShell virtual directory points to.

-InternalUrl

The InternalUrl parameter specifies the internal URL that the PowerShell virtual directory points to.

Type:Uri
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-Name

The Name parameter specifies the name of the new PowerShell virtual directory. The name you provide will have the name of the website it's created under appended to it. If the name you provide contains spaces, enclose the name in quotation marks (").

Type:String
Position:1
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-RequireSSL

The RequireSSL parameter specifies whether the PowerShell virtual directory should require that the client connection be made using Secure Sockets Layer (SSL). The valid values are $true and $false. The default value is $true.

Type:Boolean

Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-Role

The Role parameter species the configuration for the virtual directory. Valid values are:

  • ClientAccess: Configure the virtual directory for the Client Access (frontend) services on the Mailbox server.
  • Mailbox: Configure the virtual directory for the backend services on the Mailbox server.

Client connections are proxied from the Client Access services to the backend services on local or remote Mailbox servers. Clients don't connect directly to the backend services.

Type:VirtualDirectoryRole
