Windows 10 pro setup using Office 365 Essentials email - unable to use email

I'm trying to deploy a Windows 10 Pro install but at the point where it wants you to provide an email address to use for login, it refuses to accept an Office365 essentials email address. The options are to use an existing MS account or create a new one - both won't accept the email addy.

Do Office265 essentials users really create a Google account (or other free email account) and use that just to get Windows installed? Seriously?? Is there any way to join this computer to an Azure AD domain without first logging in with another email address?
