Microsoft Purview | Information Protection: Enhanced OCR support for embedded images for Microsoft Exchange Online

Microsoft Purview | Information Protection’s OCR capabilities will be enhanced to scan embedded images in files for sensitive content in Exchange Online, with a rollout starting mid-January 2025 for Public Preview and mid-February 2025 for General Availability.

With this rollout, we will enhance the OCR capabilities to scan for sensitive content in images embedded in other files (such as a .png image file in a Microsoft Word .docx file) with a limit of 20 embedded images scanned per file for Microsoft Exchange Online. Before this rollout, OCR was able to scan standalone images only. This message is associated with Microsoft 365 Roadmap ID 323899.
