Microsoft Defender 365 - Quarantine
Hi to all, I have problem with High Confidence Phish on my tenant. Many inbound mails are blocked and sent to quarantine. I release around 100 emails with false positive case in the last few days...
Hi there, sorry to hear that but I am having exactly the same issue.
Would like to know more about your environment and what you are using.
There was a change from Microsoft and it is this one:
You can find that by easily going into the Message Center from Admin portal.
In short, the policy default setting was changed from None to High Confidence Phish.
So if you were using the "Default" option, now instead of "None" you have High Confidence.
I am currently working with an Escalation engineer from Microsoft to resolve the issues on our side as we changed the setting to "none" but issue still exists.
