New-AddressRewriteEntry

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 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.

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.

The ExternalAddress parameter specifies the final email addresses that you want. If the InternalAddress parameter specifies a single email address ([email protected]), the ExternalAddress parameter must also specify a single email address ([email protected]). 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.

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

• Single email address: [email protected]
• Single domain: contoso.com or sales.contoso.com
• Domain and all subdomains: *.contoso.com

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

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 [email protected] is rewritten to [email protected], the proxy address [email protected] must be configured on Laura's mailbox. This allows replies and inbound messages to be delivered correctly.

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.
