 [!INCLUDE [Public Preview Disclaimer](../../includes/public-preview-include-document.md)]
 
-Microsoft Teams administrator can configure policies for data loss prevention (DLP) to prevent leakage of sensitive information from Teams users during Teams meetings. Developers have the option to integrate chat functionality in Teams meetings with Azure Communication Services. This can be done either through the Azure Communication Services UI library or through a custom integration. This article describes how to incorporate data loss prevention without a UI library.

 You need to set up your application to listen for real-time updates on message edits. If a Teams user sends a message containing sensitive content, the message will be automatically replaced with a blank message and flagged with a "policyViolation" result. Your application should update its user interface to reflect that the message has been blocked. For example, display a message such as "Message was blocked as it contains sensitive information." Be aware that there may be a brief delay, usually a couple of seconds, between when a message is sent and when a policy violation is detected and applied. You can find an example of such code below.
