Get message body using JavaScript API for Office

Question

I'm working on a simple mail app and I need to get the body of a message. MSDN says, version 1.1 of JavaScript API for Office has body property for message object and it can be get like this:

Office.context.mailbox.item.body;

but the problem is that I need to access the body in read mode and MSDN states that:

Read mode: The body property is undefined.

Why is the body property undefined in read mode and How can I access it? (if possible)

Answer 1

message.body or Office.context.mailbox.item.body returns Body type. Try to use this to get body text.

Office.context.mailbox.item.body.getAsync('text', function (async) {console.log(async.value)});

Answer 2

Here is getBody function. it has used CoercionType type

function getBody() {
        var _item = Office.context.mailbox.item;
        var body = _item.body;

        // Get the body asynchronous as text
        body.getAsync(Office.CoercionType.Html, function (asyncResult) {
            if (asyncResult.status !== Office.AsyncResultStatus.Succeeded) {
                // TODO: Handle error
            }
            else {
                // Show data

                console.log('Body', asyncResult.value.trim());
            }
        });
    }

but above function is part of mailbox requirement set 1.3. however this function will not work in outlook mac because it minimum mailbox requirement is 1.1
