Recommendations and best practices

Set cPanel Email Routing correctly

In cPanel → Email Routing, select Remote Mail Exchanger to ensure email traffic is routed to Microsoft 365 only.

Remove old DNS entries

Delete outdated MX, SPF, autodiscover, or webmail-related records to avoid conflicts.

Enable DKIM and DMARC

These records improve deliverability and reduce spam issues.

Use the Outlook apps

Outlook for iOS and Android offers the most reliable performance with Microsoft 365 features.

Retain the onmicrosoft.com admin account

Do not delete the default admin user. It serves as a fallback if domain issues occur.

Summary

Setting up Microsoft 365 Business email for a domain hosted in cPanel involves creating your Microsoft account, verifying your domain with TXT records, configuring all required MX and CNAME entries, enabling security features such as MFA, and ensuring proper email routing. Once DNS propagates, mailboxes can be added and configured on iOS and Android devices. Following the steps above ensures reliable email delivery, secure authentication, and full integration of Microsoft 365 services with your domain.
