Detailed Description

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 "Autodiscover virtual directory settings" entry in the Clients and Mobile Devices Permissions topic.

Parameters

Parameter Required Type Description

Identity

Required

Microsoft.Exchange.Configuration.Tasks.VirtualDirectoryIdParameter

The Identity parameter specifies the name of the virtual directory and the website. This parameter can also be used to specify the Client Access server if it's being run from another Exchange 2013 server.

BasicAuthentication

Optional

System.Boolean

The BasicAuthentication parameter specifies Basic authentication on the Autodiscover virtual directory.

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.

DigestAuthentication

Optional

System.Boolean

The DigestAuthentication parameter specifies Digest authentication on the Autodiscover virtual directory.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.

ExtendedProtectionFlags

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The ExtendedProtectionFlags parameter is used to customize the options you use if you're using Extended Protection for Authentication. The possible values are:

None Default setting.
Proxy Specifies that a proxy is terminating the SSL channel. A Service Principal Name (SPN) must be registered in the ExtendedProtectionSPNList parameter if proxy mode is configured.
ProxyCoHosting Specifies that both HTTP and HTTPS traffic may be accessing the Client Access server and that a proxy is located between at least some of the clients and the Client Access server.
AllowDotlessSPN Specifies whether you want to support valid SPNs that aren't in the fully qualified domain name (FQDN) format, for example ContosoMail. You specify valid SPNs with the ExtendedProtectionSPNList parameter. This option makes extended protection 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 Specifies that the SPN list won't be checked to validate a channel binding token. This option makes Extended Protection for Authentication less secure. We generally don't recommend this setting.

ExtendedProtectionSPNList

Optional

Microsoft.Exchange.Data.MultiValuedProperty

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

The possible values are:

Null This is the default value.
Single SPN or comma delimited list of valid SPNs By default, you must specify the fully qualified domain name (FQDN) (for example mail.contoso.com) for each SPN. If you want to add an SPN that's not an FQDN (for example, ContosoMail), you must also use the ExtendedProtectionTokenChecking parameter with the AllowDotlessSPN value. You specify the domain in SPN format. The SPN format is <protocol>/<FQDN>. For example, a valid entry could be HTTP/mail.contoso.com.

ExtendedProtectionTokenChecking

Optional

Microsoft.Exchange.Data.Directory.SystemConfiguration.ExtendedProtectionTokenCheckingMode

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

None Extended Protection for Authentication won't be used. Connections between the client and Exchange won't use Extended Protection for Authentication on this virtual directory. This is the default setting.
Allow Extended Protection for Authentication will be used for connections between the client and Exchange on this virtual directory if both the client and server support Extended Protection for Authentication. Connections that don't support Extended Protection for Authentication on the client and server will work, but may not be as secure as a connection using Extended Protection for Authentication.

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

Require Extended Protection for Authentication will be used for all connections between clients and Exchange servers for this virtual directory. If either the client or server doesn't support Extended Protection for Authentication, the connection between the client and server will fail. If you set this option, you must also set a value for the ExtendedProtectionSPNList parameter.

Note:
If you have a proxy server between the client and the Client Access server that's configured to terminate the client-to-proxy SSL channel, you must also configure one or more SPNs using the parameter ExtendedProtectionSPNList.

LiveIdBasicAuthentication

Optional

System.Boolean

This parameter is reserved for internal Microsoft use.

LiveIdNegotiateAuthentication

Optional

System.Boolean

This parameter is reserved for internal Microsoft use.

OAuthAuthentication

Optional

System.Boolean

This parameter is reserved for internal Microsoft use.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.

WindowsAuthentication

Optional

System.Boolean

The WindowsAuthentication parameter specifies Integrated Windows authentication on the Autodiscover virtual directory.

WSSecurityAuthentication

Optional

System.Boolean

The WSSecurityAuthentication parameter specifies whether to enable the WS-Security (Web Services Security) endpoint element in the Autodiscover Web.config file. The value can be set to $true or $false.
