There are two schools with a tenant each and by intune managed devices, also two different domains.
to login with email@example.com at a device, which is registered at school2.
And vice versa, login with firstname.lastname@example.org at a device, registered in the school 1 tenant.
Reason: teachers work in school 1 as well as school2 and do not want to use different logins.
Is there a way to manage this?
