In Outlook Appointment Compose mode
Office.context.mailbox.item.saveAsync(function (result) {
app.showNotification(result.value);
});
Is not returning the itemid anymore, but rather some strange string (ex: CLCID:M9_1473129000000_1473130800000__Busy_false_false) and then the whole addin and appointment dialog is closing. Seems to be a bug introduced by a OWA update? Works fine in the Outlook desktop version. Is there any workarounds to save an item and get the itemid?
