Description

This cmdlet contains more than one parameter set. You may only use parameters from one parameter set, and you may not combine parameters from different parameter sets. For more information about how to use parameter sets, see Cmdlet parameter sets.

The Set-SPWebApplication cmdlet configures the web application specified by the Identity parameter. For any settings that are zone-specific (for the Zone parameter set), the zone to configure must be provided. The provided zone must already exist.

All IIS binding settings should be respecified when updating the binding of an IIS website via the Set-SPWebApplication cmdlet. This includes the URL, secure sockets layer setting, the port number, the host header, and the certificate. If a binding setting isn't respecified, it will revert to its default value.

For permissions and the most current information about Windows PowerShell for SharePoint Products, see the online documentation at SharePoint Server Cmdlets.

Examples

EXAMPLE 1

$credentials = Get-Credential
Set-SPWebApplication -Identity http://servername -SMTPServer mail.example.com -SMTPServerPort 587 -OutgoingEmailAddress user@example.com -ReplyToAddress replyto@example.com -SMTPCredentials $credentials

This example sets the http://servername web application to use the SMTP server mail.example.com, the SMTP server port 587, the from address user@example.com, the reply-to address replyto@example.com, and the credentials stored in the $credentials object.

EXAMPLE 2

Set-SPWebApplication -Identity http://servername -SMTPServer mail.example.com -OutgoingEmailAddress user@example.com -ReplyToAddress replyto@example.com -SMTPCredentials $null

This example sets the http://servername web application to use the SMTP server mail.example.com, the default SMTP server port, the from address user@example.com, the reply-to address replyto@example.com, and to connect to the SMTP server anonymously.

Parameters

-AdditionalClaimProvider

Adds a specific claim provider to the defined web application.

Type:SPClaimProviderPipeBind[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:SharePoint Server Subscription Edition
-AllowLegacyEncryption

Specifies that older SSL and TLS protocol versions and cipher suites are allowed to be used with this IIS website. Legacy encryption is weaker than modern encryption and is not recommended.

This feature requires Windows Server 2022 or higher. This feature is not available when SharePoint is deployed with earlier versions of Windows Server.

This parameter is only valid when used with the SecureSocketsLayer parameter.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:SharePoint Server Subscription Edition
-AssignmentCollection

Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.

Type:SPAssignmentCollection
Position:Named
Default value:None
Accept pipeline input:True
Accept wildcard characters:False
Applies to:SharePoint Server Subscription Edition
-AuthenticationMethod

Use to set a web application to classic Windows authentication. The valid values are NTLM or Kerberos.

Default value:None
Accept pipeline input:False
Accept wildcard characters:False

-Certificate

Specifies the certificate that will be used for the Secure Sockets Layer (SSL) binding of this IIS website, or for authenticating to an SMTP server to send email.

When configuring the Secure Sockets Layer (SSL) binding of this IIS website, this parameter is only valid when used with the SecureSocketsLayer parameter. When configuring SMTP authentication, this parameter is only valid when the DisableSMTPEncryption parameter is not specified.

Type:SPServerCertificatePipeBind
Position:Named

Type:SwitchParameter
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:SharePoint Server Subscription Edition
-HostHeader

Specifies the host header binding for this IIS website. A host header binding allows multiple IIS websites to share the same port number. Web requests sent to a shared port number are routed to the correct IIS website based on the value of the HTTP host header sent by the client.

If no host header binding is specified, then all web requests sent to this port number will be routed to this IIS website unless another IIS website has a host header binding that matches the HTTP host header sent by the client.

Type:String
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:SharePoint Server Subscription Edition
-Identity

Specifies the name or URL of the web application.

The type must be a valid name, in the form WebApplication-1212, or URL, in the form https://example.contoso.com.

Position:1
Default value:None
Accept pipeline input:True
Accept wildcard characters:False

Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:SharePoint Server Subscription Edition

Enables Secure Sockets Layer (SSL) encryption for this web application. If you choose to use SSL, you must import a server certificate to SharePoint and assign it to the IIS website for this web application. Until this is done, the web application will be inaccessible from this IIS website.

The default value is False.

If this parameter is omitted or set to False, this web application will use HTTP for the specified port.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:SharePoint Server Subscription Edition
