Outlook Addin Event handler clean up

Question

I am having problems with the event handler in my office addin . Below is an example code i got from microsoft website to explain what i mean. I have a manifest file that uses the on-send hook as well as a click-based event triggering. My button calls appendMessageBodyOnClick and onsend i call appendMessageBodyOnSend. Both function primarily do the same thing. I never want to block sending emails regardless. The problem is that the event object is not properly cleaned up i think. Scenario 1 When i click my button ; which calls event.completed(), and then after i try to send the message, it says my app is blocking the message, but then when i try to send again it goes through. Scenario 2 When i leave the subject empty and then send the message, as expected i am prompted that the subject is empty. If i cancel sending the message on this note and then click on my button, the message tries to send as though i clicked send. I am supposing the is some sort or state clean up issue. What am i doing wrong here? Function-File.js function appendMessageBodyOnClick(event) { // Append string to message body event.completed(); } // In the following example, the checkMessage function has // been registered as an event handler for ItemSend. function appendMessageBodyOnSend(event) { // Append string to message body event.completed({allowEvent = true}); } JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Not sure if this will help, but I also have faced some seemingly inconsistent behavior while understanding how to signal that event is fully completed. Once I got my edge cases fixed, then it worked. One suggestion: Appending string to message body should be an async function. Call the event.completed() from inside the callback function. (i.e: make sure when you are calling event.completed(), nothing else is pending -like another async result) Something like the following: Office.context.mailbox.item.body.setAsync("new body", function(asyncResult) { // handle success and failure event.completed() }); Same would be for your scenario 2, make sure event.completed() is called at the very end.
