summary for non-techies**
Microsoft Defender for Office 365 is introducing new features such as the ability to submit suspicious emails or files for analysis, a tenant-level block feature to prevent known threats, and triggering investigation actions from Advanced Hunting to enhance digital security and threat management.
Direct effects for Operations**
Increased Risk of False Positives
Without proper preparation, the new submission and blocking features may lead to an increase in false positives, causing legitimate emails to be blocked or flagged incorrectly, which can disrupt business communication.
