ATP does not consider mails from other Office 365 tenants, or even mailboxes inside of your tenant, as safe. The best way to put a stop to this is to follow the recommendations in SecureScore for your tenant; and report phishing mails to us promptly.Tony commented
Can we get a site that we can report compromised tenants?
I just got one, also use ATP and the link takes you to a compromised tenant which redirects to a different site to harvest credentials.
It should be a way we can report these sites and someone should be able to take immediate action
