The unauthenticated sender ‘?’ comes to Outlook

About a year ago, in Office 365, we released the feature that - similar to Gmail - Outlook Web Access stamps a '?' in the sender photo when the message is not authenticated with either SPF or DKIM.

Well, I was pleasantly surprised to see this morning it's also in Outlook (for Windows, not sure about other clients):

This is great to see, we're now managed to unify the behavior between both Outlook and Outlook Web Access, at least in Office 365.

Woot!

11/1/2018 - Clarification: this feature is actually still in Preview.
