When setting up an email account, you may receive the "pending setup: validating MX record" while the system verifies your email account is using the correct MX records. If the MX records are correct, the message disappears. If the message remains, the MX records you specified in your hosting provider or domain name system manager may be incorrect. Your hosting provider is where your domain is hosted; your domain name system manager is a third-party domain manager where you might manage your domain settings, such as your DNS servers or MX records.
If the MX records are incorrect, you can add the correct MX records in your hosting provider or third-party domain name system manager.
To Change the MX Record
Log on to your hosting provider or third-party domain name system manager.
Change your MX records to:
MX 0 - smtp.secureserver.net
MX 10 - mailstore1.secureserver.net
