MicrosoftJeremyTBradshaw This configuration you mention is overridden. As AndAufVCG and myself have mentioned, there's no notification for HCP, it's been turned off no matter how you configure it, it's documented to be the case.
In addition, while I appreciate you setting that up for a very large client, the SMB's that grew Office when no large client would touch O365 have been left behind with undelivered mail, no notice, no NDR on the sending side and an email gatekeeper they didn't ask for and can't opt out of... It's a breach of the service contract in it's current config. And most importantly, those SMB's don't have admins policing a quarantine. They want it in Junk Mail like Outlook has done, not this whole recruitment into training the AI they are attempting to get for free from customers. Customers simply submit marketing messages from their competitors and boom, those marketing messages don't get delivered any more, and they are no where NEAR being a phishing attempt.. much of what Microsoft has high confidence as phishing is low confidence.
- Phishing is a type of social engineering attack often used to steal user data, including login credentials and credit card numbers. It occurs when an attacker, masquerading as a trusted entity, dupes a victim into opening an email, instant message, or text message.
Emails from my existing customers and contacts are NOT phishing attempts...
By the way, why are the HCP settings under anti-spam when there's an anti-phishing section?
Nobody in the small and mid-size customer base even know a quarantine exists because up until end of last year, everything went to Junk Mail. Microsoft decided to be the mail police with these new policies but didn't inform anybody except partners hidden inside hundreds of other partner notifications of new "features".
It's gotta get fixed
