M365 Changelog: (Updated) Microsoft Defender for Office 365 enable admins to provide intent while submitting

MC696850 – Updated February 25, 2024: Microsoft has updated the rollout timeline below. Thank you for your patience.

This applies to customers with Exchange Online Protection, Microsoft Defender for Office plan 1 or plan 2 service plans.

Soon, admins can provide intent when submitting messages (email and Microsoft Teams), email attachments, or URLs to Microsoft.

Admins can convey whether they are submitting for a second opinion from Microsoft or they are submitting because a true malicious message was missed by Microsoft. With this change, Microsoft analysis of admin submitted messages (email and Microsoft Teams), URLs, and email attachments will be further streamlined and will result in more accurate analysis.

This new feature will not impact any existing submissions, filtering, or grouping functionality in submissions.
