RM543969Microsoft Purview: Information Protection-Email attachment Preview in Activity Explorer

We're enhancing Activity Explorer to provide greater visibility into sensitive data flagged in Exchange Online. Previously, only the message body was viewable, which limited insight into flagged content. With this update, admins will be able to preview email attachments directly within Activity Explorer—without needing to download the email.
