Starting September 2025, Outlook for Web and new Outlook for Windows will stop displaying inline SVG images, showing blank spaces instead. This affects under 0.1% of images, improves security, and requires no user action. SVG attachments remain supported. Organizations should update documentation and inform users.
Updated September 30, 2025: We have updated the timeline. Thank you for your patience.
Introduction
We're retiring support for inline SVG images in Outlook for Web and the new Outlook for Windows starting early September 2025. This change enhances security and aligns with current email client behavior, which already restricts inline SVG rendering.
