JeremyTBradshaw Unfortunately, this is inaccurate information you've provided. Yes, the documentation says it's true, but it's not. HCP has the three qualities mentioned above: Not in Anti-Phishing as it should be, not able to be filtered other than Quarantine, and does not notify user when it's quarantined.
Roadmap or not, it's a not a 'feature', its a necessity they notify users they are withholding mail or stop withholding it and put it back in Junk Mail until it's complete, because as of now, you are disallowed from doing so. You have to go into the policy, try to change it, and you'll see the warning saying it's disallowed.
I understand you have good intentions of trying to be helpful, but the issue here is how you think it works and how Microsoft now makes it work since the end of January are two different things, and the scoring system is marking far more items as anti-phishing than it should, using the anti-spam policy to do so. They do the same thing with Malware, where they don't deliver it and don't notify you, but they've lumped HCP in to the same bucket and their high confidence is very low confidence and highly over scored. If a customer I work with sends me a message, there is no way it should ever score above a 5; yet it sometimes will score an 8 because it has KnowBe4 in an attached Excel sheet or doesn't follow some draconian measure Microsoft wants you to adhere to simply to get your mail. The customer and I are both on O365 and properly configured; it's the scoring that's broken. Heck, it even scores it's own emails from the O365 Mail Migration Batch reporting as HCP...
I appreciate your time, but I do promise, what I've said above is how things have been working for the past couple of months, and AndAufVCG seems to be seeing the same thing. I also have tickets open for this and they are not fixing it. Check it out yourself.
Here's one to check with the full Outlook client installed:
In Outlook, click the 'Junk Mail' folder
Now, type in a search term at the top from a trusted source Email address removed.
Even though you selected Junk Mail and Outlook knows you mean the Junk Mail folder, it still gives you results from everywhere. In addition, click a result, and you'll see 'Links and other functionality have been disabled...' come up on that message even though it's not in the Junk Mail folder...
The roapmap needs a significant review and adjustment, and the existing features blocking email or the scoring of those emails and the classification of what's phishing and what isn't need to be re-evaluated long before the roadmap task is completed.
