일부 도메인에서 Professional Email를 사용할 수없는 이유는 무엇인가요?

As you set up your Professional Email account, you might see some domains listed as not eligible or grayed out in your Email & Office Dashboard. This is because you can only have a one type of email account for each domain.

For example, you'll get an error message if you try to set up a Professional Email account with a domain that's already used by Microsoft 365.
