    Hi Srinivasa,

    Html format provider can be customized such as you can handle an event each time an image should be loaded from URL. Here is some code that demonstrates the approach:

    HtmlFormatProvider provider = new HtmlFormatProvider();
    var myHtmlImportsettings = new HtmlImportSettings();
    myHtmlImportsettings.LoadImageFromUrl += new EventHandler<LoadImageEventArgs>(myHtmlImportsettings_LoadImageFromUrl);
    provider.ImportSettings = myHtmlImportsettings;
    void myHtmlImportsettings_LoadImageFromUrl(object sender, LoadImageEventArgs e)
        //Get stream from e.Url here:
        //then load the image with the appropriate extension
        e.ImageElement.Init(inputStream, "png");

    The problem in your case would be to get the image from the Exchange server. You may try doing this via Silverlight WebClient and a separate web-service that would provide the images given the exchange image url. Unfortunately we do not have any experience with such a task.

    All the best,
