How do I change the MX records for my domain name?

This article will show you how to point your domain name to a different email account.

MX records (Mail eXchanger records) are a type of DNS record that directs email traffic for your domain. They tell services like Microsoft 365 where to send emails meant for your domain.

Before you get started, you’ll first need to ensure your domain is pointed to the 123 Reg nameservers. Otherwise, any configurations you’ve made to the DNS through our Control Panel will not take effect.

Please note: Changing your MX records may interrupt email services that are connected to your domain. Be careful and double check all settings before adding, amending, or deleting MX records.
Please note: it will take between 24-48 hours for any new nameserver (DNS) records to become active.

Once you’ve done this, simply follow these instructions:

  1. Start by logging in to your 123 Reg Control Panel.
  2. From there, open the Domains section and select DNS opposite the domain name you want to change the DNS records for.
    Select domain
  3. You will now be taken to the DNS Management page for your domain name. Scroll down to find the MX record you wish to edit. Then, select the Edit icon (represented as a pencil) next to your MX record.
    Edit MX record
  4. You can now change your MX record’s details. These should be provided by your email service provider.
    5. Click save
  5. One you've done this, click Save to confirm your changes.

    6. Alternatively, you can point your domain name to your MX record via the Advanced DNS tab. However, this is a more intricate process that is recommended for advanced users only.
