Unfortunately, adding a custom domain to create personalized email addresses is not possible with a Microsoft 365 Family Plan. This feature is only available for business and enterprise plans, like Microsoft 365 Business Basic, Microsoft 365 Business Standard, or Microsoft 365 E3.
Starting November 30, 2023, Microsoft 365 Family subscriptions no longer allow creating new personalized email addresses with your own domain for use with Outlook.com. This functionality was previously available as a benefit, but it is no longer offered.
However, there are alternative options to consider:
Upgrade to Microsoft 365 Business or Microsoft 365 Apps: These subscriptions still allow connecting your own domain and creating email addresses associated with it.
Continue using your current Microsoft 365 Family email address: If you already have a personalized email address created before November 30, 2023, you can continue using it as before.
Here are some options to consider:
- Continue using the existing Microsoft domain: Your Family Plan already provides email addresses with the "@outlook.com******************" domain. While not personalized, these email addresses still offer access to all the core features of Outlook.
- Upgrade to a business plan: If personalized email with a custom domain is essential for you, consider upgrading to a Microsoft 365 business plan. These plans offer features like custom domains, shared calendars, and additional security features.
I understand this might not be the answer you were hoping for, but I hope it helps clarify the limitations of the Family Plan and provides alternative options to consider.

I hope this information helps! If I can be of help with anything else, please let me know. I will be glad to answer any other questions that you might have.
