Event element
Defines an event handler in an add-in. For information about support and usage, see On-send feature for Outlook add-ins.
Note
Smart Alerts, which is a newer version of the on-send feature, uses the LaunchEvents element to configure an add-in for event-based activation. To learn more about the key differences between Smart Alerts and the on-send feature, see Differences between Smart Alerts and the on-send feature. We invite you to try out Smart Alerts by completing the walkthrough.
