Imagine Microsoft Teams as a large office building where everyone communicates and collaborates. In this building, there are security guards (Microsoft Defender) who are responsible for ensuring that only safe and appropriate messages are exchanged. Sometimes, these guards might mistakenly flag a harmless conversation as a potential threat, much like a security guard might stop someone for a routine check even if they are not carrying anything suspicious.

To address this, Microsoft Teams has introduced a new feature that allows users to report messages they believe were incorrectly flagged as security concerns. This is similar to having a suggestion box where employees can inform the security team if they think a particular check was unnecessary. This feedback helps the security team improve their accuracy and ensures that communication flows smoothly without unnecessary interruptions.

This feature is available across various platforms such as Android, Desktop, iOS, Mac, and Web, and can be used in different types of chats, including one-on-one, group, meeting chats, and channels, whether public or private. It is part of the broader Microsoft Defender for Office 365 suite, which aims to protect users from security threats while allowing them to report any false alarms.

By enabling users to report these incidents, Microsoft Teams not only enhances security but also empowers users to have a say in the process, much like giving employees a voice in the security protocols of their workplace. This approach helps create a more efficient and user-friendly environment, ensuring that security measures are both effective and minimally intrusive.
