Can I use custom domains with Microsoft 365 Business Standard email?

Yes, Microsoft 365 Business Standard allows you to use custom domains with email, enabling businesses to send and receive emails using a professional domain (e.g., yourname@yourcompany.com). Configuring a custom domain enhances brand consistency and trust in communications.

Steps to Set Up a Custom Domain in Microsoft 365 Business Standard

1. Purchase or Use an Existing Domain

• Options:
  • Purchase a new domain from a domain registrar like GoDaddy, Namecheap, or Google Domains.
  • Use an existing domain you already own.
• Ensure you have access to the domain's DNS settings for configuration.

2. Add the Domain in Microsoft 365

• Steps:
  1. Log in to the Microsoft 365 Admin Center with an admin account.
  2. Navigate to Settings > Domains.
  3. Click Add domain.
  4. Enter your domain name (e.g., yourcompany.com) and click Next.

3. Verify Ownership of the Domain

• Why: Verifying ensures you own the domain and can manage its settings.
• Steps:
  1. Microsoft will provide a TXT record or MX record for DNS verification.
  2. Log in to your domain registrar's DNS management portal.
  3. Add the provided TXT or MX record to your domain's DNS settings.
  4. Return to the Microsoft 365 Admin Center and click Verify.
  • Verification may take a few minutes to a few hours depending on DNS propagation.

4. Update DNS Records

• Steps:
  1. Microsoft will provide the necessary DNS records, including:
     • MX record: Directs email to Microsoft 365 servers.
     • CNAME records: Supports Outlook AutoDiscover and other services.
     • TXT record: Helps with email security and spam prevention (e.g., SPF record).
     • SRV record: Configures Skype or Teams communication.
  2. Add these records to your domain registrar’s DNS settings.
  3. Save the changes and allow time for DNS propagation.

5. Set the Custom Domain as Default

• Steps:
  1. Go back to the Domains section in the Admin Center.
  2. Select your custom domain and click Set as default.
  3. Assign the custom domain to user accounts:
     • Navigate to Users > Active users.
     • Edit each user's email address to reflect the custom domain (e.g., change user@onmicrosoft.com to user@yourcompany.com).

Benefits of Using a Custom Domain

1. Professional branding: Builds trust and credibility with clients and partners.
2. Centralized management: Easily manage domain-related email accounts and settings within Microsoft 365.
3. Enhanced security: Built-in tools like SPF, DKIM, and DMARC help prevent email spoofing and phishing.
4. Scalability: Add new users and accounts under your custom domain as your organization grows.
