At my work email, which is handled by MS Office 365 Outlook, I keep getting phishing emails, typically 3 times a week, usually with some attachment "your company's monthly financial report" or "voicemail recording - high priority", or "proforma invoice". All of that is obvious BS, because none of that applies to me.

Those attachments are nearly always thinly disguised html files that would (presumably) forward me to an imitation log-in web page, or present a log-in via some script. Sometimes the phishing email even tries to legitimize the fake login script, saying "a login will be required to see the attachment".

A few times I uploaded the suspected phishing attachment to VirusTotal, and it's always being reliably detected as a phishing or malicious attachment.

I can't fathom why MS Outlook isn't capable of detecting and blocking these easy-to-identify phishing emails.

Just for kicks, I tried forwarding one such email to my personal Gmail account, but Gmail smartly and immediately declined to deliver it, replying "Remote Server returned '552-5.7.0 This message was blocked because its content presents a potential 552-5.7.0 security issue."

Come on, Outlook. What's your issue? Why do you keep delivering phishing emails to my inbox that would be detected by Google, VirusTotal, or a random six year child? With all of today's machine learning, Outlook still just can't do it??? 

I religiously keep clicking the "report phishing" in Outlook, but these emails keep coming.

If there's anything I can do to improve this situation, please let me know.

Very frustrated about this.
