Set-OutlookAnywhere

This cmdlet is available only in on-premises Exchange.

Use the Set-OutlookAnywhere cmdlet to modify Outlook Anywhere virtual directories that are used in Internet Information Services (IIS) on Microsoft Exchange servers. Outlook Anywhere uses virtual directories that contain "rpc" in the name.

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

Description

For more information about the different authentication methods that you can see in this article, see Understanding HTTP Authentication.

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

Set-OutlookAnywhere -Identity:CAS01\Rpc (Default Web Site) -ClientAuthenticationMethod:Ntlm

In Exchange 2010, this example sets the client authentication method to NTLM for the /rpc virtual directory on the Client Access server CAS01.

Example 2

Set-OutlookAnywhere -Identity: "EXCH1\rpc (Default Web Site)" -ExternalClientAuthenticationMethod NTLM

This example sets the client authentication method to NTLM for the Outlook Anywhere virtual directory on the server named EXCH1.

Example 3

Set-OutlookAnywhere -Identity "EXCH1\rpc (Default Web Site)" -SSLOffloading $false -InternalClientsRequireSsl $true -ExternalClientsRequireSsl $true

This example sets the SSLOffloading parameter to $false for the Outlook Anywhere virtual directory on the server named EXCH1. This setting informs Outlook Anywhere to expect no SSL decryption between clients and the server, and enables the Require SSL value on the virtual directory. Because SSL is now required for Outlook Anywhere connections, we need to configure internal and external clients to use SSL.

Example 4

Set-OutlookAnywhere -Identity "EXCH1\rpc (Default Web Site)" -IISAuthenticationMethods NTLM

This example sets the authentication method for the Outlook Anywhere virtual directory setting in IIS to NTLM.

Example 5

Set-OutlookAnywhere -Identity "EXCH1\rpc (Default Web Site)" -IISAuthenticationMethods Basic,NTLM

In Exchange 2010 and Exchange 2013, this example sets the available authentication methods for the /rpc virtual directory setting in IIS to use both Basic and NTLM authentication. After you set this value, you can use the IIS virtual directory to handle authentication for multiple applications that require different authentication methods.

Parameters

-ClientAuthenticationMethod

This parameter is available only in Exchange Server 2010.

The ClientAuthenticationMethod parameter specifies the authentication method that the Autodiscover service provides to the Outlook Anywhere clients to authenticate to the Client Access server. Valid values are:

  • Basic
  • Ntlm

Although you can use this parameter to set only one authentication method, the command won't return an error if you include multiple values.

Type:AuthenticationMethod
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010

-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
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-DefaultAuthenticationMethod

The DefaultAuthenticationMethod parameter specifies the default authentication method for Outlook Anywhere. This parameter replaces the existing ExternalClientAuthenticationMethod, InternalClientAuthenticationMethod and IISAuthenticationMethods property values with the value you specify. Valid values are:

  • Basic
  • Ntlm
  • Negotiate

You can't use this parameter with the ExternalClientAuthenticationMethod, InternalClientAuthenticationMethod and IISAuthenticationMethods parameters.

Type:AuthenticationMethod
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, 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
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, 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
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, 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
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, 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

-SSLOffloading

The SSLOffloading parameter specifies whether a network device accepts SSL connections and decrypts them before proxying the connections to the Outlook Anywhere virtual directory on the Exchange server. Valid values are:

  • $true: Outlook Anywhere clients using SSL don't maintain an SSL connection along the entire network path to the Exchange server. A network device in front of the server decrypts the SSL connections and proxies the unencrypted (HTTP) client connections to the Outlook Anywhere virtual directory. The network segment where HTTP is used should be a secured network. This is the default value.
  • $false: Outlook Anywhere clients using SSL maintain an SSL connection along the entire network path to the Exchange server. Only SSL connections are allowed to the Outlook Anywhere virtual directory.

This parameter configures the Require SSL value on the Outlook Anywhere virtual directory. When you set this parameter to $true, Require SSL is disabled. When you set this parameter to $fase, Require SSL is enabled. However, it may take several minutes before the change is visible in IIS Manager.

You need to use the value $true for this parameter if you don't require SSL connections for internal or external Outlook Anywhere clients.

The value of this parameter is related to the values of the ExternalClientsRequireSsl and InternalClientsRequireSsl parameters.
