Microsoft has announced that very soon, Teams users will be able to report when a legitimate message is mistakenly flagged as a “threat.” In other words, if the system detects something as malicious when it’s not, the user will be able to report it directly.
This feature began limited testing in September, and Microsoft has confirmed that its global rollout is scheduled for the end of November 2025.
According to the update published in the Microsoft 365 Message Center, “Microsoft Teams now allows users to report messages they believe were incorrectly flagged as security threats in chats and channels.”
The company explains that this feedback process helps reduce false positives and improves the accuracy of its detection systems, which also strengthens the overall security of the organization.
The ability to report false positives will be available to companies using Microsoft Defender for Office 365 Plan 2 or Microsoft Defender XDR. Additionally, it will be accessible across all platforms: desktop (Windows and macOS), mobile devices (Android and iOS), and the web version of Teams.
How to Enable or Disable the New Feature from Microsoft Teams Admin Settings
Once the feature becomes available to all users, it will be enabled by default in Teams. However, admins will be able to easily turn it on or off from the Teams Admin Center or directly from the Microsoft Defender portal.

To enable reporting of incorrect security detections, admins just need to follow a few very simple steps:
-
Sign in to the Teams Admin Center.
-
In the side menu, go to “Messaging Policies.”
-
Scroll down to the “Messaging Security” section.
-
Enable the option “Report Incorrect Security Detections.”
-
Save the changes to apply the configuration.
In addition to this new feature, Microsoft has been introducing other functions focused on strengthening security within Teams. Just a few days ago, it began rolling out an exclusive option for Premium customers that automatically blocks screen recordings and screenshots during meetings.
Microsoft has also announced that Teams will display warnings when a user sends or receives private messages containing potentially malicious links, and that they are working to improve protection against suspicious files and URLs within chats and channels.
All of these enhancements are already in the process of being rolled out globally and are expected to be available to all users by the end of November 2025.
During last year’s Enterprise Connect conference, Microsoft revealed that Teams has over 320 million monthly active users across 181 markets—a figure that highlights the importance of continuing to strengthen its security.
