What do I need to do to use my own domain name with outlook for business?

Hi,

This is April, I'll be happy to assist you. Sorry to hear that you're having issue with Microsoft domain. Let me help you out.

Based on the description of the issue you provided, you want to use your own domain names with Outlook for Business so that emails sent by you and your users show your custom domain in the "Reply-To" address instead of your ISP's email addresses.

Do you want Outlook for Business to fully host and deliver email through your custom domain?

To use a custom domain with Outlook for Business, you first add the domain to Microsoft 365 and verify ownership by updating your DNS records. You then configure the required email settings such as MX, SPF and DKIM so email is properly routed through your domain. Once this complete, you can assign domain-based email address (for example, ******@yourdomain.com) to users and start using them as the Reply-To address in Outlook right away.

Here are step-by-step Guide:

1. Prepare your Domain
   • Make sure you own a registered domain
   • Confirm you can access DNS settings through your domain registrar (example, GoDaddy, Namecheap, IONOS).
2. Add the Domain to Microsoft 365
   • Sign in to the Microsoft 365 Admin Center
   • Navigate to Setup > Domains > Add domain
   • Enter your domain name (for example, yourcompany.com)
   • Microsoft will generate DNS records for verification.
3. Verify Domain Ownership
   • Add the provided TXT record to your domain's DNS settings.
   • Allow time for DNS propagation (typically a few minutes to several hours).
   • Once verified, Microsoft 365 will confirm ownership of the domain.
4. Configure Email DNS Records To enable sending and receiving email through Outlook:
   • MX record: Route incoming mail to Microsoft 365 mail servers.
   • SPF record: Authorize Microsoft servers to send mail on your behalf and prevent spoofing.
   • DKIM and DMARC (optional but recommended): Improve email security and deliverability.
5. Create User Email Accounts
   • In the Admin Center, create users and assign email addresses using your domain.
   • Examples:
   • ******@yourdomain.com
   • ******@yourdomain.com
   • Each user can sign in to Outlook using their domain-based email.
6. Set the Default "From" or Reply-to-Address in Outlook
   • In Outlook (desktop or web):
   • Go to File > Account Settings > Email > Change.
   • Set the domain email address as the default account.
   • Alternatively, configure a custom Reply-To address under More Settings > Advanced.
7. Test and Confirm

• Send test emails to external addresses (such as Gmail or Yahoo).
• Verify that the From and Reply-To fields display your domain email correctly.

I hope this helps. If you need further assistance you can reply to this message.
