MC469568: Introducing Threat Explorer V3 by Microsoft Defender for Office 365

We are happy to share that Microsoft Defender for Office 365 is rolling out the Threat Explorer-Version 3. Threat Explorer has been an integral part of security operations workflow allowing users to explore the email data and take remediation actions on threats. And we strive to make the security operations experience better for the users by enhancing the filtering, navigation and data visualization experiences.

With this new version, we are improving the filtering experience by adding four new filtering conditions. The existing “Advanced Filters” functionality has been made available with the new filter, thereby reducing the complexity in applying multiple filter conditions and providing users an easy to navigate and rich filtering experience.
