Method Details

completed(options)

Indicates that the add-in has completed processing and will automatically be closed.

This method must be called at the end of a function which was invoked by the following:

  • A function command button (that is, an add-in command defined with an <Action> element, where the xsi:type attribute is set to ExecuteFunction).

  • An event defined in the Events extension point of an on-send add-in in Outlook. For example, an ItemSend event.

completed(options?: EventCompletedOptions): void;

Parameters

options
Office.AddinCommands.EventCompletedOptions

Optional. An object that specifies the behavior of an on-send add-in in Outlook when it completes processing an ItemSend event.

Returns

void

Remarks

The following outlines support information for Outlook.

[ API set: Mailbox 1.3 ]

Minimum permission level: restricted

Applicable Outlook mode: Compose or Read

Important: The options parameter only applies to Outlook add-ins that implement the on-send feature. It was introduced in Mailbox 1.8.

Examples

// For the following example, the processItem function is
// defined in the FunctionFile referenced from the add-in manifest,
// and maps to the FunctionName of the action in the associated button control.
function processItem(event) {
    // Do some processing.

    event.completed();
}
// In this example, the checkMessage function was registered as an event handler for ItemSend.
function checkMessage(event) {
    // Get the item being sent.
    const outgoingMsg = Office.context.mailbox.item;

    // Check if subject contains "BLOCK".
    outgoingMsg.subject.getAsync(function (result) {
        // Subject is in `result.value`.
        // If search term "BLOCK" is found, don't send the message.
        const notFound = -1;
        const allowEvent = (result.value.indexOf('BLOCK') === notFound);
        event.completed({ allowEvent: allowEvent });
    });
}
