Following the documentation in several places [mostly on Microsoft here: https://docs.microsoft.com/en-us/javascript/api/office/office.addincommands.event?view=office-js and here: https://docs.microsoft.com/en-us/outlook/add-ins/add-in-commands-for-outlook but also from various searches etc] I am unable to get the UI Less Functions to work in Outlook Desktop or Outlook Web Access.

Both appear to call the function-file as I can test that and successfully see output from the Office.Initilize function. But I can never get the actual named function to call at all.

I've seen lots of examples and can't find anyone else complaining that it doesn't work so must be doing something wrong but I can't spot the fault:

function-file.js:

// The initialize function must be run each time a new page is loaded

Office.initialize = reason => {

    console.log('Office init...' + reason);

};



// Add any ui-less function here

function testEventObject(event) {

    var buttonId = event.source.id;

    console.log('testEventObject() called, buttonID: ' + buttonId);

    event.complete();

}

What I actually get:

Browser Console Log

Hopefully something simple I'm missing!

Per documentation on FunctionFile element, event should call method completed(). The function you have posted has syntax error as it calls to event.complete();. This needs to be addressed.

The functionFile element pointed to "https://localhost:3000/function-file/function-file.html", but script snapshot in the description is for function-file.js. Please check you are correctly included JS file into your HTML file. For example, if you used absolute URI to the resource it has to start with https (SSL). Also, try to leave inside this JS file only functions you need, to avoid any other JS errors.
