The Phish Alert button is great for reporting messages to our helpdesk, and for notifying users when they report a phish test email. It does nothing for actually improving our mail filters to prevent such messages from getting through in the future though. Microsoft offers a Report Message function which submits suspicious messages to them for the purpose of improving the Office 365/Exchange Online Protection filters, but that doesn't check to see if the message is a phish test and notify the users that they caught one.
I can't tell users to submit messages using Microsoft's button if they think it's just spam, but PAB if they think it's phishing. Is there any other way to get the functionality of PAB while also submitting the message to Microsoft for review?
