Detailed Description

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Accepted domains" entry in the Mail Flow Permissions topic.

Parameters

Parameter	Required	Type	Description
DomainName	Required	Microsoft.Exchange.Data.SmtpDomainWithSubdomains	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.
Name	Required	System.String	The Name parameter specifies a unique name for the accepted domain object.
AuthenticationType	Optional	Microsoft.Exchange.Data.Directory.AuthenticationType	This parameter is reserved for internal Microsoft use.
CatchAllRecipient	Optional	Microsoft.Exchange.Configuration.Tasks.RecipientIdParameter	This parameter is reserved for internal Microsoft use.
Confirm	Optional	System.Management.Automation.SwitchParameter	The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.
DomainController	Optional	Microsoft.Exchange.Data.Fqdn	The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.
DomainType	Optional	Microsoft.Exchange.Data.Directory.SystemConfiguration.AcceptedDomainType	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`.
InitialDomain	Optional	System.Boolean	This parameter is reserved for internal Microsoft use.
LiveIdInstanceType	Optional	Microsoft.Exchange.Data.Directory.LiveIdInstanceType	This parameter is reserved for internal Microsoft use.
MailFlowPartner	Optional	Microsoft.Exchange.Configuration.Tasks.MailFlowPartnerIdParameter	This parameter is reserved for internal Microsoft use.
Organization	Optional	Microsoft.Exchange.Configuration.Tasks.OrganizationIdParameter	The Organization parameter is reserved for internal Microsoft use.
OutboundOnly	Optional	System.Boolean	The OutboundOnly parameter specifies whether this accepted domain is an internal relay domain for the on-premises deployment for organizations that have coexistence with a cloud-based organization. The authoritative accepted domain for the on-premises deployment is configured as an internal relay accepted domain on the cloud side. If the on-premises deployment is using Microsoft Forefront Online Protection for Exchange, you must set this parameter to `$true` for the accepted domain that represents your on-premises deployment. This parameter is used only if the DomainType parameter is set to `Authoritative` or `InternalRelay`. The default value is `$false`.
SkipDnsProvisioning	Optional	System.Management.Automation.SwitchParameter	This parameter is reserved for internal Microsoft use.
WhatIf	Optional	System.Management.Automation.SwitchParameter	The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
