Introduction to accepted domain
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. Next, 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 addressed to @exoip.com recipients.
Add accepted domain in Exchange Admin Center
Sign in to Exchange Admin Center as administrator or with an account with the privileges to create the accepted domain in Exchange.
Navigate to mail flow > accepted domains. Click the + icon.
Fill in the Name field and Accepted domain field. Click Save.
Note: You can’t make the domain as default when creating a new domain. You have to make the domain as default after you create the new accepted domain.
In our example, it’s the domain exoip.com.
Click on the domain that you added. Click the edit icon.
Select Make this the default domain checkbox. Click the Save button.
Confirm that the domain shows as default.
