Every student here has a school email account, and some use that for the Apple Store, and some/most do not. I am trying to invite students to use VPP, and need to be able to send this email invite to their school email address, and when they click on the link, they can pick which address to use, e.g if they open the link on their iPad they will be asked to login to whatever account they use.
Is this possible? I hope so.
