Answer 2

Hello, @IniobongNkanga-8038,

Welcome to the Microsoft Q&A platform!

The documentation provided by Andy David is comprehensive and effective, I'm just going to give you a few notes and ways to contact your DNS provider.

If you want to set up DMARC Records in Microsoft 365, you need to create SPF TXT records and configure DKIM signing for all custom domains and subdomains that you use to send email in Microsoft 365 before you configure DMARC for custom domains or subdomains. For more information, please refer to Set up SPF identify valid email sources for your Microsoft 365 domain - Microsoft Defender for Office 365 | Microsoft Learn and How to use DKIM for email in your custom domain - Microsoft Defender for Office 365 | Microsoft Learn.

To learn how to contact your DNS provider, you could refer to Who Is A DNS Hosting Provider? How Do I Find The DNS Hosting Provider Of My Domain? (intermedia.com).
