Hi @Sangkamkad, Petcharat

To set a user's primary email address, please follow these steps:

1. In the admin center, go to the Users > Active users page.
2. Select the user's name, and then on the Account tab select Manage username. In the first box, type the first part of the new email address. If you added your own domain to Microsoft 365, choose the domain for the new email alias by using the drop-down list. Learn how to add a domain.
3. Select Save changes.

For more details, you could refer to: Change a user name and email address - Microsoft 365 admin | Microsoft Learn.
