Set-ActiveSyncVirtualDirectory

The ActiveSyncServer parameter specifies the URL of the Mailbox server. This value is in the following format: https://servername/Microsoft-Server-ActiveSync.

The BadItemReportingEnabled parameter specifies whether items that can't be synchronized should be reported to the user. If set to $true, the user receives a notification when an item can't be synchronized to the mobile phone.

The BasicAuthentication parameter specifies whether Basic authentication is enabled on the virtual directory. Valid values are:

• $true: Basic authentication is enabled. This is the default value.
• $false: Basic authentication is disabled.

The ClientCertAuth parameter specifies the status of client certificate authentication. By default, client certificate authentication is disabled. The default setting is Ignore.

The CompressionEnabled parameter is a Boolean value that identifies the compression applied to the specified Exchange ActiveSync virtual directory. The default setting is $true.

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 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.

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.

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.

The ExternalAuthenticationMethods parameter restricts the authentication methods that can be used to connect to the virtual directory from outside the firewall. Valid values are:

• Adfs
• Basic
• Certificate
• Digest
• Fba
• Kerberos
• LiveIdBasic
• LiveIdFba
• LiveIdNegotiate
• NegoEx
• Negotiate
• Ntlm
• OAuth
• WindowsIntegrated
• WSSecurity

You can specify multiple values separated by commas.

Although you can specify any of these values, whether or not the authentication method actually works for external connections depends on other factors. For example:

• Is the authentication method available on the virtual directory?
• Is the authentication method available, but disabled on the virtual directory?

The ExternalURL parameter specifies the URL that's used to connect to the virtual directory from outside the firewall.

The Identity parameter specifies the ActiveSync virtual directory that you want to modify. You can use any value that uniquely identifies the virtual directory. For example:

• Name or Server\Name
• Distinguished name (DN)
• GUID

The Name value uses the syntax "VirtualDirectoryName (WebsiteName)" from the properties of the virtual directory. You can specify the wildcard character (*) instead of the default website by using the syntax VirtualDirectoryName*.

The InstallIsapiFilter parameter specifies whether the Internet Server API (ISAPI) filter is installed.

The InternalAuthenticationMethods parameter specifies the authentication methods supported by the server that contains the virtual directory when access is requested from inside the network firewall. If this parameter isn't set, all authentication methods can be used.

The InternalURL parameter specifies the URL that's used to connect to the virtual directory from inside the firewall.

The MobileClientCertificateAuthorityURL parameter specifies the URL for the certification authority (CA) used by the mobile phone.

The MobileClientCertificateProvisioningEnabled parameter specifies whether the Autodiscover service returns the Certificate Services server URL in the XML file.

The MobileClientCertTemplateName parameter specifies the template name for the client certificate.

The Name parameter specifies the name of the Exchange ActiveSync virtual directory.

The RemoteDocumentsActionForUnknownServers parameter specifies the action that occurs when a Microsoft Windows SharePoint Services or Microsoft Windows file share request comes in via Exchange ActiveSync. When a request arrives, Exchange ActiveSync looks for the requested host name in the Allow and Block lists. If the host name isn't found in either list, the action specified in this parameter, either Block or Allow, is performed.

The RemoteDocumentsAllowedServers parameter is a multivalued property that lists all the allowed servers for remote document access.

The RemoteDocumentsBlockedServers parameter is a multivalued property that lists all the blocked servers for remote document access.

The RemoteDocumentsInternalDomainSuffixList parameter is used in organizations that don't run Windows Internet Name Service (WINS) in their network. In these environments, you can specify one or more FQDNs that Exchange ActiveSync treats as internal when a request for remote file access is received.

The SendWatsonReport parameter specifies whether a Watson report is sent for errors and events.

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.

The WindowsAuthEnabled parameter specifies whether Integrated Windows authentication is enabled. The default value is $false.
