If the original organization removes the binding with an old domain, will the work accounts that use the old domain and belong to the original organization still remain under the original organization's management?

If the original organization removes the binding with an old domain, will the work accounts that use the old domain and belong to the original organization still remain under the original organization's management?

For example, in the case of Intune, will they still be subject to the original organization's device management?

Additionally, if a new organization binds to a domain that was previously unbound by the old organization, will the work accounts using the old domain automatically associate with the new organization?

If so, if the new organization enables automatic MDM management, will devices automatically register for device management?

Thank you in advance and looking forward to your reply!
