為什麼我的某些網域不符合Professional Email的資格？
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.
以下內容無法轉移到其他平台：
- Professional Email
- Microsoft 365
