Microsoft Office 365
Setting up a domain and email in Microsoft 365 Admin Center involves verifying your domain, configuring DNS settings, and setting up email services in Exchange Online. The process begins by adding your domain to the Admin Center and verifying ownership using a TXT record from your domain registrar. Once verified, essential DNS records (MX, CNAME, SPF, and SRV) must be updated to ensure proper email routing and service functionality. After DNS configuration, users can be created, assigned licenses, and configured for Exchange Online to send and receive emails. Additional security measures, such as multi-factor authentication (MFA) and mail flow rules, can be implemented to enhance email security. Proper configuration ensures seamless email communication and integration with Microsoft 365 services.
Configuring a domain and email in Office 365 (Microsoft 365) Admin involves several steps, including domain verification, DNS setup, and email configuration. Here’s a step-by-step guide:

Type the domain you want to add (e.g., yourdomain.com).
Click “Use This Domain”.
Verify Your Domain
Microsoft provides a TXT record.
Copy the TXT record and add it to your domain registrar’s DNS settings (GoDaddy, Namecheap, Cloudflare, etc.).
After adding the TXT record, return to Microsoft 365 and click “Verify”.
Configure DNS Records
Once the domain is verified, Microsoft will prompt you to update the required DNS records for email and other services.
