New-AddressRewriteEntry

This cmdlet is available or effective only on Edge Transport servers in on-premises Exchange.

Use the New-AddressRewriteEntry cmdlet to create an address rewrite entry that rewrites sender and recipient email addresses in messages sent to or sent from your organization through an Edge Transport server.

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

Syntax

New-AddressRewriteEntry
   [-Name] <String>
   -ExternalAddress <String>
   -InternalAddress <String>
   [-Confirm]
   [-DomainController <Fqdn>]
   [-ExceptionList <MultiValuedProperty>]
   [-OutboundOnly <Boolean>]
   [-WhatIf]
   [<CommonParameters>]

Description

On Edge Transport servers, you need to be a member of the local Administrators group to run this cmdlet.

Examples

Example 1

New-AddressRewriteEntry -Name "Address rewrite entry for david@contoso.com" -InternalAddress david@contoso.com -ExternalAddress david@northwindtraders.com

This example creates an address rewrite entry that rewrites the email address david@contoso.com to david@northwindtraders.com in outbound mail. Because the OutboundOnly parameter is not set to $true, inbound mail sent to david@northwindtraders.com is rewritten back to david@contoso.com.

Example 2

New-AddressRewriteEntry -Name "Address rewrite entry for all contoso.com email addresses" -InternalAddress contoso.com -ExternalAddress northwindtraders.com

This example creates an address rewrite entry that rewrites all email addresses in the contoso.com domain to northwindtraders.com in outbound mail. Because the OutboundOnly parameter is not set to $true, inbound mail sent to northwindtraders.com recipients is rewritten back to contoso.com.

Example 3

New-AddressRewriteEntry -Name "Address rewrite entry for contoso.com and all subdomain email addresses" -InternalAddress *.contoso.com -ExternalAddress northwindtraders.com -ExceptionList research.contoso.com,corp.contoso.com -OutboundOnly $true

This example creates an address rewrite entry that rewrites all email addresses in the contoso.com domain and all subdomains to northwindtraders.com. However, email addresses in research.contoso.com and corp.contoso.com are not rewritten. Because this address rewrite entry affects a domain and all subdomains (*.contoso.com), address rewriting occurs on outbound mail only.

Parameters

-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

-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.

The DomainController parameter isn't supported on Edge Transport servers. An Edge Transport server uses the local instance of Active Directory Lightweight Directory Services (AD LDS) to read and write data.

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

-ExceptionList

The ExceptionList parameter specifies the email address domains that shouldn't be rewritten when the InternalAddress parameter contains the wildcard character to rewrite addresses in a domain and all subdomains (*.contoso.com). You can enter multiple domain values in the ExceptionList parameter separated by commas.

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

-ExternalAddress

The ExternalAddress parameter specifies the final email addresses that you want. If the InternalAddress parameter specifies a single email address (chris@contoso.com), the ExternalAddress parameter must also specify a single email address (support@contoso.com). If the InternalAddress parameter specifies a single domain (contoso.com) or a domain and all subdomains (*.contoso.com), the ExternalAddress parameter must specify a single domain (fabrikam.com).

You can't use the wildcard character (*) with the ExternalAddress parameter.

Type:String
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-InternalAddress

The InternalAddress parameter specifies the original email addresses that you want to change. You can use the following values:

  • Single email address: david@contoso.com
  • Single domain: contoso.com or sales.contoso.com
  • Domain and all subdomains: *.contoso.com
Type:String
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-Name

The Name parameter specifies a unique name for this address rewrite entry.

Type:String
Position:1
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-OutboundOnly

The OutboundOnly parameter enables or disables outbound-only address rewriting. Valid input for this parameter is $true or $false. The value $true means address rewriting occurs in outbound mail only. The value $false means address rewriting occurs on outbound mail and also on inbound mail (rewritten email addresses are changed back to the original email addresses in inbound mail). The default value is $false.

You must set this parameter to $true if the InternalAddress parameter contains the wildcard character to rewrite addresses in a domain and all subdomains (*.contoso.com).

Also, when you configure outbound-only address rewriting, you need to configure the rewritten email address as a proxy address on the affected recipients. For example, if laura@sales.contoso.com is rewritten to laura@contoso.com, the proxy address laura@contoso.com must be configured on Laura's mailbox. This allows replies and inbound messages to be delivered correctly.

Type:Boolean
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

-WhatIf

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.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
