Answer 1

I believe you are using Microsoft Threat Management , this is an informational report from the Threat Management and it is about "Generates an alert when Microsoft detects a user’s Junk Mail folder is disabled, allowing delivery of a high confidence phishing message to a mailbox. This policy has an Informational severity setting." , take a look at:

Depending on what email application or webmail is being used, you have to enable the Junk Mail folder, take a look at:

Answer 2

Hi there,

It is the new security policy by Microsoft.

You will now be alerted when a message is delivered, only when it is determined with a high degree of confidence that it is phishing or malware, to a mailbox because of a policy that was enabled/disabled.

The alert policies will be enabled by default but you can turn them on/off as needed. You will also have the ability to define who gets the alerts and also manage how many alerts are sent to help control false positives.
