Update MX Records in GoDaddy DNS Settings

Add the correct Microsoft 365 MX record to your GoDaddy domain settings and remove conflicting records to properly route incoming emails to your mailbox.

An MX (Mail Exchanger) record tells the internet which mail servers accept incoming emails for your domain. If this record is missing or pointing to the wrong server, your outgoing emails will still work, but incoming emails will bounce or fail to deliver.

Find your Microsoft 365 MX record

Sign in to the Microsoft 365 admin center. Go to 'Settings' and then 'Domains'. Select your custom domain, click on 'DNS records', and locate your specific MX record value (usually formatted similarly to yourdomain-com.mail.protection.outlook.com).

Access GoDaddy DNS Management

Log in to your GoDaddy account. Navigate to your 'Domain Portfolio', select your custom domain, and click 'DNS' to open the DNS Management page.

Add the new MX record

Click 'Add New Record' and select 'MX' from the type dropdown. Enter '@' for the Name, paste the Microsoft 365 MX value into the Value field, and set Priority to 0. Click 'Save'.

Remove conflicting records

Review your existing DNS records for any old or duplicate MX records pointing to previous email hosting providers and delete them to prevent routing conflicts.

Wait for propagation and test

Allow time for the DNS changes to propagate across the internet (typically 15-30 minutes, though it can take up to 48 hours). Afterward, run an inbound SMTP test or send a test email to your address to verify.

Update MX Records in GoDaddy DNS Settings

Verification Complete: Once the correct MX record propagates and is detected by Microsoft 365, your domain status in the admin center will update to 'Healthy'.

Frequently Asked Questions

How long does it take for GoDaddy MX records to update?

DNS propagation usually takes 15 to 30 minutes. However, depending on your region and local internet service provider, it can sometimes take up to 48 hours for the new MX records to be recognized globally.

Can I have multiple MX records for my custom domain?

While you can have multiple MX records for backup servers belonging to the same email provider, having conflicting MX records from different hosts (like a previous web host and Microsoft 365 simultaneously) will cause email delivery failures.

Where can I run an inbound SMTP test to check my emails?

You can run connectivity and inbound SMTP tests using the Microsoft Remote Connectivity Analyzer tool provided by Microsoft to officially diagnose and verify email routing issues.
