Summary:
Microsoft Defender for Office 365 is changing the subject line format for end-user reported notification messages to improve readability and rule creation. The rollout starts mid-June 2024 and ends mid-July 2024. No action is required from users as existing settings remain unaffected.

Details:
Updated June 6, 2024: We have updated the rollout timeline below. Thank you for your patience.
Currently, in Microsoft Defender for Office 365, when a notification message is reported by an end user and arrives at the reporting mailbox, the subject lines begin with:
"1|" to denote email messages reported as junk.
"2|" to denote email messages reported as not junk.
"3|" to denote email messages reported as phishing.
Moving forward, the subject lines of notification messages reported by end users will start with
"Junk:" to denote email messages reported as junk.
"Not junk:" to denote email messages reported as not junk.
"Phishing:" to denote email messages reported as phishing.
This change is being made to ensure readability and enable you to create better rules inside your reporting mailbox.
The subject line for the team's end-user reported notification messages will remain the same, continuing to start with "Security risk:"
[When will this happen:]
General Availability (Worldwide, GCC, GCC High, DoD): We will begin rolling out mid-June 2024 (previously late May) and expect to complete mid-July 2024 (previously mid-June).
