# [Web and Windows (new)](#tab/web)

In Outlook on the web and the new Outlook on Windows, create a handler in your JavaScript file for the [Office.EventType.DragAndDropEvent](/javascript/api/office/office.eventtype) event using the [Office.context.mailbox.addHandlerAsync](/javascript/api/outlook/office.mailbox#outlook-office-mailbox-addhandlerasync-member(1)) method. When the `DragAndDropEvent` event occurs, the handler receives a [DragAndDropEventArgs](/javascript/api/outlook/office.draganddropeventargs) object so that you can identify when a user drags an item over the task pane, when they drop the item into the task pane, and what data is associated with the item. Depending on whether a drag or drop event occurred, the [dragAndDropEventData](/javascript/api/outlook/office.draganddropeventargs#outlook-office-draganddropeventargs-draganddropeventdata-member) property of the `DragAndDropEventArgs` object returns a [DragoverEventData](/javascript/api/outlook/office.dragovereventdata) or [DropEventData](/javascript/api/outlook/office.dropeventdata) object. These objects provide information on the position of the mouse pointer and the data being transferred to the task pane.

Both these objects provide information on the position of the mouse pointer. Note that only the `DropEventData` object contains the data being transferred to the task pane.

When messages are dragged to the task pane, they're dropped as .eml files. Attachments that are dropped retain their current format. For a list of supported types, see [Supported item types](#supported-item-types).
