Add Your Custom Domain to Your Microsoft Entra Tenant

Introduction

Microsoft Entra tenants come with a default domain name, but you can add your organization's custom domain to enhance user familiarity and provide a more professional appearance. This guide will provide step-by-step instructions on how to add your custom domain to your tenant.

Prerequisites

• Create your custom domain name through a domain registrar.
• Create your Microsoft Entra directory.

Step 1: Add Your Custom Domain Name

1. Sign in to the Microsoft Entra admin center as a Domain Name Administrator.
2. Navigate to Identity > Settings > Domain names > Add custom domain.
3. Enter your custom domain name (e.g., dynamicendpoints.com) and click Add domain.

Step 2: Verify Domain Ownership

1. The unverified domain will appear with DNS information.
2. Go to your domain registrar and create a TXT or MX record based on the DNS information provided.
3. Set the time to live (TTL) to 3600 seconds (60 minutes) and save the record.

Step 3: Verify Custom Domain Name

1. Return to the Microsoft Entra admin center.
2. Navigate to Identity > Settings > Domain names.
3. Select your custom domain name and click Verify.

Common Verification Issues

• Wait at least an hour for DNS propagation.
• Ensure the DNS record is correct and matches the information provided in the Microsoft Entra admin center.
• Verify that the domain name is not already in use in another directory.
• Ensure you have no unmanaged Power BI tenants.

Benefits of Adding a Custom Domain

• Familiar usernames (e.g., randy@daynamicendpoints.com)
• Enhanced brand recognition
• Professional appearance

Next Steps

• Add additional Global Administrators to your directory.
• Add users to your domain.
• Manage your domain name information in Microsoft Entra ID.
• Integrate your on-premises directories with Microsoft Entra ID (if applicable).

By following these steps, you can seamlessly add your custom domain to your Microsoft Entra tenant, providing a more personalized and professional experience for your users.
