Creating an addin for Outlook using javascript

Question

I've seen the jello-dashboard for Outlook which adds Getting Things Done (GTD) functionality to Outlook. I'm taken by the fact that it only uses javascript to do this (using extjs). Previously I thought that any add-in dev for MS products were obliged to use VBA on C# or one of the other MS technologies. I've looked through some of the jello-dashboard js files but haven't been able to see (or understand) where it uses what I presume is an API to modify Outlook behaviour.

This is all in the hope of creating an add-in which will add delicious.com like functionality to Outlook, i.e. filtering of e-mails using a tag-cloud approach (based on Outlook categories)

I'd appreciate if anyone has pointers on where I could find the information/examples/tutorials on this javascript => Outlook hookup. I've had no luck on das web but starting from a point of ignorance my searches may be badly formed.

Best regards / Colm

Outlook AddIns are fundamentally COM. What I suspect this AddIn is doing is embedding a [`IWebBrowser2`](http://msdn.microsoft.com/en-us/library/ie/aa752127%28v=vs.85%29.aspx) to host Internet Explorer inside of Outlook and they handle external JavaScript events in their document via COM. — vcsjones, Feb 21 '12 at 16:53

Jello isn't really an add-in, per se. What it is doing is basically using a trick. That trick is to create a new folder in Outlook. Then, right click on the new folder and select properties. Then click on the "Home Page" tab. Check the box that says "Show home page by default for this folder". Then in Address type in the address of an html page. E.g., C:\test.html.

Here is some code I whipped up that will show you the subject of the newest message in your inbox that you can paste into C:\test.html

<script>

    var ol = window.external.OutlookApplication;

    function GetCurrentItem(){  
        var ns=ol.GetNameSpace("MAPI");
        var inbox=ns.GetDefaultFolder(6);
        var items = inbox.Items;
        items.Sort("ReceivedTime", true);
        alert(items(1).Subject);    
    }

</script>


<input type=button onclick="GetCurrentItem()" value="GetCurrentItem">

Thanks for the pointer, the use of "standard" html/javascript/css opens up a whole vista of possibilities. – carbontracking Mar 28 '12 at 14:57
Any chance of doing an installable? I mean instead of having to click on creating folder and properties, etc... – Sebastian Sastre Apr 05 '13 at 14:24

As this might be slightly considered as advertisement I'm doing this a s a comment. We are in the process of building a Javascript API for Outlook which will be able to use many features of the native API, but much more stable and unified. It's called yasoon, look it up if you are interested! – mnkypete Dec 20 '13 at 10:08
