I'm trying to implement an add-in for Outlook which has some fields and a button that once clicked does some validations and sends an appointment to inform the attendees.
I am using the function below to achieve my goal:
Office.context.mailbox.item.saveAsync()
Office.context.mailbox.item.close() (as a callback for the function above)
It works for office365, but it doesn't work for office365 thick client.
I found in the Microsoft docs that with the function 'saveAsync' in Outlook in cached mode, the item is saved to the local cache. I disabled this option and still getting the same result.
I was using OnSend functionality, but this feature is not supported for Outlook client.
Any advice or tips of how could I have the functionality of sending the appointment through my Add-in in both, client and web version of Outlook? Basically I need to trigger the existing button 'Send' in the calendar.
