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 the mail exchanger (MX) records in public DNS for exoip.com. The MX records are the records of spam filter because it will route the messages to it, filter them, and then deliver them to the Exchange Server.
Note: Always use a spam filter to protect your Exchange Server organization from incoming and outgoing spam. The one we recommend is the SpamBull cloud spam filter.
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
To add an accepted domain in Exchange Admin Center, follow the below steps:
1. Sign in to Exchange Admin Center as administrator or with an account with the privileges to create the accepted domain in Exchange.
2. Navigate to mail flow > accepted domains. Click the + icon.
3. 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.
4. Click on the domain that you added. Click the edit icon.
5. Select Make this the default domain checkbox. Click the Save button.
6. Confirm that the domain shows as default domain.
Add accepted domain with PowerShell
To configure an accepted domain with PowerShell, follow these steps:
1. Run Exchange Management Shell as administrator.
2. Run the New-AcceptedDomain cmdlet and Set-AcceptedDomain cmdlet.
In our example, it will create the new default domain exoip.ia.
[PS] C:\>New-AcceptedDomain -Name "exoip.ai" -DomainName "exoip.ai" -DomainType Authoritative | Set-AcceptedDomain -MakeDefault $true
If you like to add a new accepted domain without making it default, remove the Set-AcceptedDomain cmdlet.
[PS] C:\>New-AcceptedDomain -Name "exoip.ai" -DomainName "exoip.ai" -DomainType Authoritative
Name DomainName DomainType Default
---- ---------- ---------- -------
exoip.ai exoip.ai Authoritative False
Get accepted domains with PowerShell
Sometimes you want to get a list of the accepted domains. What is a better way than using PowerShell? Run the Get-AcceptedDomain cmdlet.
[PS] C:\>Get-AcceptedDomain
Name DomainName DomainType Default
---- ---------- ---------- -------
exoip.local exoip.local Authoritative False
exoip.com exoip.com Authoritative True
exoip.ai exoip.ai Authoritative False
That’s it!

After you add the accepted domains, you need to do the following:
1. Create an email address policy in Exchange Server.
2. Open the email address policy properties and select “apply to”.
3. Specify the types of recipients this email address policy will apply to. For example, you can select an OU (Organizational Unit).
