Remote domains are SMTP domains that are external to your Microsoft Exchange organization. You can create remote domain entries to define the settings for message transfer between your Exchange organization and domains outside your Active Directory forest. The settings for remote domains are global configuration settings for the Exchange organization.

Prerequisites

You can't create a remote domain that has the same name as an already configured accepted domain. For example, if your organization accepts mail for fabrikam.com, you can't create a remote domain for fabrikam.com.

What Do You Want to Do?

Use the EMC to create a remote domain

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Remote domains" entry in the Transport Permissions topic.

  1. In the console tree, navigate to Organization Configuration> Hub Transport.

  2. In the result pane, click the Remote Domains tab.

  3. In the action pane, click New Remote Domain. The New Remote Domain wizard appears.

  4. On the New Remote Domain page, complete the following fields:

    • Name   Use this field to identify the remote domain in the user interface. You can type any name that you want. We recommend that you select a meaningful name that helps you easily identify the purpose of this remote domain. You must use a unique name for each remote domain. The name can't exceed 64 characters. This field is required.

    • Domain Name   Use this field to identify the SMTP namespace of the remote domain. For example, type contoso.com. The remote domain name can't exceed 256 characters. This field is required.

    • Include all subdomains   To apply the remote domain configuration to all subdomains of the remote domain, such as mail.contoso.com, select this check box.

    • Use this domain for my Office 365 tenant   If the new remote domain you're creating represents the part of your organization that is hosted on Microsoft Office 365, select this check box.

  5. To create the remote domain entry with these settings, click New.

  6. On the Completion page, review the following, and then click Finish to close the wizard:

    • A status of Completed indicates that the wizard completed the task successfully.

    • A status of Failed indicates that the task wasn't completed. If the task fails, review the summary for an explanation, and then click Back to make any configuration changes.

Use the Shell to create a remote domain entry

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Remote domains" entry in the Transport Permissions topic.

You use the New-RemoteDomain cmdlet to create new remote domains in your organization. This example shows how this cmdlet can be used to create a new remote domain for contoso.com.

Copy Code 
New-RemoteDomain -Name Contoso -DomainName Contoso.com
