Adding a second user using Azure AD to a windows 10 device?

Hi all,

I would like to add multiple users to a windows device using AAD.

The first user is easy enough and they are an administrator.

Subsequent users I can not figure out for the life of me.

If you go to add a new user via friends and family it is a local account or a Microsoft account ( FYI you can no longer create a Microsoft account using an O365 email address )

I know this can be done but I am blowed if I can figure it out.

I know this is not what AAD is meant for but this will help a customer out bigtime if we can get it to work.

Thanks

John
