Addressing the Need for Multiple Records for Domain Verification

I have lost track of how many times I've had to heed the call "verify my domain." Sometimes it's more than four times a day from different emails. Having to jump from resolving an issue to verifying the domain can naturally fix some issues, like not receiving emails, not able to send emails, being unable to send emails to public folders, and more in #M365.

However, one misconception I would like to address is the notion that multiple records are required for domain verification.

I have been asked by some people a couple of times why we need three different records to verify domains for Microsoft 365 instead of just one. Some have even suggested that providing the domain should be enough evidence that one owns it. However, the reason behind requiring multiple records is to ensure the security, reliability, and proper configuration of your Microsoft 365 account.

Now, let's briefly explore each record and its significance in setting up and verifying your domain for Microsoft 365.

MX Record: ?

MX (Mail Exchange) records specify the mail servers responsible for receiving email on behalf of your domain. In the context of Microsoft 365, MX records ensure that emails sent to your domain are routed to Microsoft's mail servers. This is essential for proper email delivery and management within your #M365 account.

TXT Record:

TXT (Text) records serve multiple purposes, including domain verification and email authentication. For Microsoft 365, TXT records are used to verify domain ownership and configure email authentication mechanisms such as SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail). They provide additional security and help prevent email spoofing and phishing attacks.

CNAME (Autodiscover) Record:

The CNAME autodiscover record is essential for automatic configuration of email clients and other services in Microsoft 365. By pointing the autodiscover hostname to Microsoft's autodiscover service, this record allows email clients to automatically detect the correct settings for connecting to your Microsoft 365 mailbox. This ensures a seamless setup experience for users and reduces the need for manual configuration.

By implementing these three types of DNS records, you ensure the proper functioning, security, and ease of use of your Microsoft 365 account for email communication and other services.
