explanation for non-techies**

Imagine you have a secure filing cabinet where only certain people can access specific folders. Each time someone opens a folder, you keep a record of who accessed it and what they did. Now, let's say some of these folders contain sensitive information, and you want to ensure that even the records of who accessed them don't reveal too much about the contents.

In the world of IT, Microsoft Purview is like that secure filing cabinet, and the records of access are called audit events. Recently, Microsoft announced improvements to how these audit events are handled for columns with special security settings, known as column-level security. This means that when someone accesses or changes information in these protected columns, the records will be more careful about what details they show.

Before these changes, audit events might have included information that could hint at the sensitive data in those columns. With the new enhancements, the details in these records will be filtered, so they don't reveal sensitive information. Think of it as redacting certain parts of a document before sharing it, ensuring that only the necessary information is visible.

These changes will take effect on December 1, 2025, and you might notice that the records for these secure columns will be less detailed. However, this is intentional to protect sensitive information better. No action is required on your part, but it's good to be aware of these updates to understand why some records might look different in the future.
