how should schools manage a small pod of leased ipad pro devices

They are ipad pro devices - our teachers want to try ipad pro rather than windows devices as per the rest of the school. My issue is that they are leased, so we didnt buy them and the teachers have already used their azure (intune and active directory) school email addresses with things like apple store. So we cant use their school emails as managed apple id's - wondering what other schools do?

Thanks for that info celliott147 its good to know that it is possible. Unfortunatly the 2 ipad pro devices arrive tomorrow and having only ever managed our school using intune devicemanagement endpoint via azure I am not sure where to start with these. I do not have an apple mac and our school cant afford to buy or lease me one. The devices are leased from a government funded agency and they haven't offered a solution apart from we should lease a mac at full price. I don't know if I should even try to manage them as they are so used to being able to purchase what they want app wise and having it right then, on their personal devices and then having full access to windows store on their work windows devices - any suggestions?

How can our school take over the apple id of past students and staff (some of whom are dead) when we don't know the answers to their security questions, but they have signed up using a old school email address which now needs to be federated?

Thank you very much this was so helpful and has answered many of my questions.

Thanks again celliott147 that was really helpful.
