Office 365 Home / Family: Does it also have a Tenant ? (Migrating to Business E3)

Hello,

Does Office 365 Home / Family also have a tenant ?

Reason i am asking: Client is using Office 365 Family to license the desktop apps and use onedrive / teams.

Mails are currently on a IMAP service.

Currently they are using personal microsoft accounts like email address removed for privacy reasons

 

I want to migrate the Client to Office 365 Busniess (E3 accounts). I have setup the tenant. Now i want to add the domain customdomain.com and i get this error:

 

Remove domain from another account

 

We can't add this domain to your account because other people have already signed up for

‎Microsoft 365‎ using an email address ending in customdomain.com.

 

Is this because their using Office 365 Family with e-mail adressess also ending in @customdomain.com ? Or did somebody added the domain to a real Office 365 Tenant ?

     I believe that every instance of M365 is considered a tenant.

    From Microsoft Support, 

    "I have a commercial Microsoft 365 subscription. Can I use the custom domain tied to my commercial email account as a personalized email address on Outlook.com?

    No. You can't use the same email address for a commercial Microsoft 365 email account and a consumer Microsoft 365 or Outlook.com account."

      Not quit sure about this. In A O365 Family / Home you can't add a custom domain. It is linked to a personal microsft account...

      Also Family / Home does not offer a EOL e-mail adress, you need a personal microsoft account
