Currently I am facing a predicament with a high volume of emails being flagged as high-confidence phishing under the "Advanced filter" detection technology by our anti-spam policy, a vast majority of which appear to be benign. I have noted the "Advanced phishing threshold" in the anti-phishing policy, which is described as "These thresholds control the sensitivity for applying machine learning models to messages to determine a phishing verdict"
I have not, however, found any concrete evidence that these 2 settings in completely different policies are in any way related. Is there any way to tune the thresholds for the "Advanced filter" detection technology?

If they are flagged as high confidence phishing, the only real option is to submit these to Microsoft as false positives:
Hello, @Zack A，
Welcome to the Microsoft Q&A platform!
Andy David - MVP is right. If emails are being consistently flagged as high-confidence phishing by Microsoft’s filtering systems, submitting these emails as false positives to Microsoft is a crucial step. This helps improve the machine learning models and reduces the likelihood of similar benign emails being flagged in the future.
Here are some points you should be aware of:
