I have an Outlook Add-In written in the new Javascript API (office.js).
I do some manipulations from the compose form on an appointment in the calendar (adding subject suffix and some text to body). After I finish the manipulations I call:
Office.context.mailbox.item.saveAsync(callback)
the item with my changes get saved, however when I call Office.context.mailbox.item.close() or just close the appointment compose form on the outlook web UI - a dialog is displayed if I want to save my changes or discard them, altough there were no changed made since the saveAsync call.
Regardless if the user clicks Save or Discard, the appointment has the changes I made with the add-in before the saveAsync call. What can be the reason for such behavior?
