    We’re investigating an issue where legitimate URL links are being incorrectly marked as malicious by the Microsoft Defender service. Additionally, some of the alerts are not showing content as expected. Further details can be found under DZ534539 within the admin center.

      We determined that recent additions to the SafeLinks feature resulted in the false alerts and we subsequently reverted these additions to fix the issue. More detail can be found in the Microsoft 365 admin center under DZ534539.

      Here’s the reality from someone who is experiencing this first hand.

      In the past week they were HUGELY missing very obvious phishing emails.  As a result of all of us complaining at how bad the detection had become, they overcompensated and then got false positives.

      They were flagging zoom call links.
