Overview

Temporal send buffer for Outlook Web email.

UNDO adds a short delay before emails are sent in Outlook Web. When the user clicks Send or uses Ctrl/⌘+Enter, UNDO briefly pauses delivery and shows an undo option. The user can cancel the send or send immediately. UNDO works only on Outlook Web. The extension runs locally in the browser and does not read message content, store data, or communicate with external servers. This extension is a standalone tool and does not promote or install other products.
