Dear Dobrosława Duszyńska
Good day!
Thank you for posting to Microsoft Community. We are glad to assist!
Based on your description, I understand you concern with to use your custom domain with Microsoft Teams and Outlook.
You may have a try to do following steps:
- Add your domain to Microsoft 365: Go to the Microsoft 365 admin center, navigate to Settings > Domains, and select Add domain. Follow the steps to verify that you own your domain and set up the necessary DNS records, you can refer to Add a domain to Microsoft 365 - Microsoft 365 admin | Microsoft Learn.
- Set Up Email Aliases: Once your domain is added, you can create email aliases for your custom domain. Go to Users > Active users. Select the user (yourself) and click on Manage email aliases. Add your custom email address (e.g.,
[email protected]) as an alias. - Set Primary Email Address: After adding the alias, you can set it as your primary email address. In the Manage email aliases section, select your custom email address and set it as the primary email.
- Configure your email account in Outlook: Ensure that your custom domain email is set up as an Exchange account in Outlook. This will allow you to send and receive emails using your custom domain email address
For @onmicrosoft.com, when you sign up for Microsoft 365, Microsoft provides an onmicrosoft.com domain - your fallback domain - in case you don't own a domain, or don't want to connect it to Microsoft 365 (for example, tailspintoys.onmicrosoft.com). Your fallback domain is used by default in:
- Usernames and email addresses
- Microsoft 365 teams & groups email aliases
- Automatic domain dependency moves
You can refer to Add and replace your onmicrosoft.com fallback domain in Microsoft 365 - Microsoft 365 admin | Microsoft Learn
If you have other questions, please feel free to let me know, I will continue to assist you.
Thanks for your precious time and your understanding would be highly appreciated. Have a nice day!

May 19, 2023I have a 365 family subscription and I own a domain. I want to create an email in outlook using my domain but I can’t find out how to do so. Do I have to have a business account?
Sigh, I'm in the same boat. Previously, the supported procedure REQUIRED Godaddy for your registrar. Recently MS announced that they are no longer going to offer new custom domains starting in 2023. Apparently you can set one up prior to the cutoff date and they will let you use the custom domain. Personally, I don't want to use Godaddy and I don't want to be in some kind of unsupported position eventually so my plan is to go with a different host someday. More on reddit.com

The information in that post is wrong.
If you have your own domain and an Microsoft 365 personal or family subscription, you can add the domain in Outlook.com's Settings (gear icon) > View all Outlook settings > Premium
https://outlook.live.com/mail/0/options/premium/personalemail
But you need to do it ASAP - before the end of Nov.
My instructions above are correct for family and personal accounts.
