The roadmap id 567316 tag covers Microsoft’s planned stale-reply warning for Outlook. The feature is intended for Outlook for Windows and Outlook on the web, where it will alert users if they choose to reply to an older message instead of the newest email in a conversation. Microsoft added the roadmap item on July 6, 2026, marking it as in development for worldwide Microsoft 365 tenants. General availability is scheduled for August 2026. This archive is focused on the feature’s rollout timing, supported Outlook experiences, and its effort to reduce replies sent from outdated points in an email thread.
