What feature of Conditional Access App Control can help prevent sensitive content from being sent in Microsoft Teams messages?

The correct choice highlights the functionality of Conditional Access App Control, particularly how it leverages real-time content inspection to help safeguard sensitive information in Microsoft Teams messages. By creating a session policy that actively monitors the content of messages as they are being sent, this approach allows organizations to effectively block messages that contain sensitive information before they can be transmitted. This proactive measure not only helps in compliance with data protection regulations but also reinforces the organization's efforts to prevent data leaks in real-time.

The emphasis on real-time content inspection differentiates this method from other approaches, such as encryption or manual monitoring. Encryption alone doesn't prevent the transmission of sensitive information; it merely secures the data in transit. Manual monitoring is resource-intensive and reactive rather than proactive, allowing potential incidents to occur before they are detected. Disabling chat functionality could hinder productivity and communication among users, making it a less favorable option. Therefore, implementing a session policy with content inspection stands out as the most effective way to manage the risk of sensitive content being shared in Teams messages.
