How to add accepted domain in Exchange 2016 and why do you want to configure accepted domain in Exchange? If you don’t configure accepted domain in Exchange, you can’t receive emails to that domain. Pretty easy, right? In this article, you will learn how to add accepted domain in Exchange 2016.

Accepted domain in Exchange information

Accepted domains are the SMTP namespaces, also known as address spaces. You configure the domain in the Exchange organization to receive email messages. In our example, we registered the domain exoip.com. We configured a mail exchanger (MX) record in public DNS for exoip.com. Now we need to configure exoip.com as an accepted domain in the Exchange organization to accept messages that are addressed to @exoip.com recipients.

Configure accepted domain in Exchange 2016

Log into Exchange Admin Center as administrator or with an account with the privileges to create accepted domain in Exchange.

Click mail flow. Click accepted domains. Click the plus icon.

Fill in the Name field and Accepted domain field. In our example, exoip.com. We can’t make the domain default when we create a new domain. We can do that in the next step. Click Save.

Click on the domain that we added. Click the edit icon.

Select Make this the default domain checkbox. Click the Save button.

Confirm that the domain is showing as default.

Add accepted domain with PowerShell

Run Exchange Management Shell as administrator. Let’s combine the New-AcceptedDomain cmdlet and Set-AcceptedDomain cmdlet. This will create a new default domain named exoip.ia.

If you like to add a new accepted domain without making it default, remove the Set-AcceptedDomain cmdlet.

Get accepted domains with PowerShell

Sometimes you want to get a list of the accepted domains. What is a better way than using PowerShell? Use the Get-AcceptedDomain cmdlet.
