Microsoft 365 roadmap entry

Summary

Outlook on the web and the new Outlook for Windows now support will support new settings for loading external images. New settings will allow customers to block all external content, or to load all content by default if the customer admin allows. Existing default behavior will not be changed (load external content only for safe senders).
