Description

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

New-AcceptedDomain -DomainName Contoso.com -DomainType Authoritative -Name Contoso

This example creates the new authoritative accepted domain Contoso.

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.

-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.

Default value:None
Required:False

Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-DomainName

The DomainName parameter specifies the SMTP domain that you want to establish as an accepted domain. Valid input for the DomainName parameter is an SMTP domain. You can use a wildcard character to specify all subdomains of a specified domain, as shown in the following example: *.contoso.com.

However, you can't embed a wildcard character, as shown in the following example: domain.*.contoso.com. The domain name string may not contain more than 256 characters.

Type:SmtpDomainWithSubdomains

Default value:None
Required:True

Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-DomainType

The DomainType parameter specifies the type of accepted domain that you want to configure. Valid values are Authoritative, InternalRelay or ExternalRelay. You must set at least one value.

In an authoritative domain, messages are delivered to a recipient that has a domain account in your Exchange organization. In an internal relay domain, messages are relayed to a server outside your Exchange organization, but still under the authority of your company or IT department. Use the internal relay domain if you want to treat the messages to this domain as internal messages. In an external relay domain, messages are relayed to an email server, outside your organization, which you don't control.

The default value is Authoritative.
