user-reported phishing emails

Feedback to users who report phishing | Microsoft Community Hub

It is extremely annoying to have to take some extra action after a user reports an email as phishing, microsoft analyzes it and determines that there is no threat, and then it just sends them an email back saying ok the email with subject blahblahblah is clean... doesnt show the sender address of the email reported, only subject, doesnt tell them to then go and search for the email or that it should be in the deleted items folder and find it, if they search the inbox it wont be found because search results dont include items in the deleted items folder, so they have done such a bad execution job with this, it's not surprising people choose alternative platforms for almost everything they can vs microsoft's own.
