Hello Shyam,

I've created a new Outlook add-in project, added an Outlook Forms Manager, added an ADXOlFrom, dropped a WebBrowserComponent on it, added the html you sent me to the resource called "Login", and wrote the following event handler of the ADXOlForm.ADXAfterFormShow event: 

        private void ADXOlForm1_ADXAfterFormShow() {
            webBrowser1.AllowWebBrowserDrop = false;
            webBrowser1.IsWebBrowserContextMenuEnabled = true;
            webBrowser1.WebBrowserShortcutsEnabled = true;
            webBrowser1.ObjectForScripting = MyAddin183.AddinModule.CurrentInstance;
            this.webBrowser1.Navigate("about:blank");
            HtmlDocument doc = this.webBrowser1.Document;
            doc.Write(String.Empty);
            this.webBrowser1.DocumentText = Properties.Resources.Login; // HTML file is reading from  Resource
        }


Note the value I assign to the ObjectForScripting property: it is a reference to the instance of the add-in module which is loaded in Outlook.

In accordance with the code of the javascript that the html page invokes, I put the following method on the module: 

        public void LoginToServer() {
            MessageBox.Show("It works", this.AddinName);
        }


When the webBrowser component on the pane shows the HTML page and I click the corresponding HTML control on the page, the LoginToServer() method above is invoked.
