Yes. I have access to any global admin accounts right now but given admin accounts @abc.com are not working. These admin accounts @abc.com work if I change their UPNs. for example @xyz.com . I need to use these accounts without changing UPNs.
Your only way to use them without changing the UPNs to a non-federated domain (like xyz.com) would be to have matching/synced accounts exist in your local AD. There's no way to exclude specific accounts from being redirected to ADFS; it's an all or nothing deal. Hope that helps and that I'm understanding your situation right. If not, let me know and I can reply back.
