    Hello

    Have you already added your domain to your business account?

    If you have added your domain successfully, go to Admin Center https://admin.microsoft.com

    Go to Users > Active Users > Your user, then in the Account tab, under Alias section, click on change username and email, then give yourself a new alias and from the dropdown, select your own domain. Then set it as primary alias. I suggest that you keep the onmicrosoft.com one, in case you have domain issue down the road, you still have this username as your plan b.

    =========

    If your domain is not added yet, you need to add it first. The instruction is here: https://learn.microsoft.com/en-us/microsoft-365/admin/setup/add-domain?view=o365-worldwide

    To ensure that your business email does not display the "onmicrosoft.com" domain when sending emails, you need to change your email address to use your custom domain (e.g., "mydomain.com"). Here are the steps to do this:

    1. Purchase a Custom Domain: If you haven't already, you need to buy a domain name that you want to use for your email address.
    2. Add Your Domain to Microsoft 365: Go to the Microsoft 365 admin center and add your custom domain. This involves verifying that you own the domain by updating DNS records with your domain registrar.
    3. Change Your Email Address: Once your domain is set up, you can change your email address to use your custom domain. This can be done in the Microsoft 365 admin center by updating your user account settings.
    4. Set Up Email Routing: Ensure that your email routing is correctly configured so that emails sent to your custom domain are directed to your Microsoft 365 account.
    5. Test Your Email: After making these changes, send a test email to confirm that it appears with your custom domain instead of the "onmicrosoft.com" domain.

    By following these steps, your emails should display your custom domain when sent to clients.
