Examples
// This example gets the Recurrence object of an appointment item.
Office.context.mailbox.item.recurrence.getAsync(callback);
function callback(asyncResult) {
    const context = asyncResult.context;
    const recurrence = asyncResult.value;
    if (!recurrence) {
        console.log("One-time appointment or meeting");
    } else {
        console.log(JSON.stringify(recurrence));
    }
}
// The following example shows the results of the getAsync call that retrieves the recurrence for a series.
// NOTE: In this example, seriesTimeObject is a placeholder for the JSON representing the
// recurrence.seriesTime property. You should use the SeriesTime object's methods to get the
// recurrence date and time properties.
