How do I verify my domain for Microsoft 365?

This article outlines the two ways with which you can verify your domain name for Microsoft 365 (formerly known as Office 365).

Before getting started, you’ll need to ensure your domain is pointed to the 123 Reg nameservers. Otherwise, you will not be able to configure the DNS zonefile.

If you haven’t already done so, you’ll need to activate your Microsoft 365 package. For more details on how to perform this, please read the following Support article: How do I activate my Microsoft 365 package?
