What does "No threats found > Phishing or Junk" mean in the User reported messages tab of Microsoft Defender?

The phrase "No threats found > Phishing or Junk" indicates that while a message may have initially raised suspicion, further analysis revealed that it is not harmful. This means that the message was likely scrutinized for possible phishing attempts or junk classification, but it was ultimately assessed and considered safe for the user. As a result, the system or administrator acknowledges that the message does not represent a security threat, aligning with the context of the answer chosen.

The other options reference different statuses that do not match this indication—such as confirmation of malicious content or the requirement for further investigation, which would signify that a threat was detected rather than ruled out. The key takeaway here is the assurance that the message is deemed harmless after scrutiny, hence supporting the rationale for the selected answer.
