Log Off OWA from Code Behind

After many tries and havey googling to find out the best way to log off OWA from asp.net page code behind while logging out from my main application, i found out that this can be achieved in one way ( in my position). Rise a small popup window and call OWA log out page!

All done with a small javascript. the script is below ;

private void LogoffOwa()
    {
        string popupScript = "<script language='javascript'>" +
   "var mywindow=window.open('https://OWA_SERVER_Adress/owa/auth/logoff.aspx?Cmd=logoff', 'CustomPopUp', " +
   "'width=1, height=1, menubar=no, resizable=no');" +
   "setTimeout(\"mywindow.close();\",3000);" +
   "</script>";
        Response.Write(popupScript);
    }

in the script you have to set the time out of the window. Do not close the window directly or you will not log off. Just give it some time to open the log off page.

Hope this helps

One of my work needs was to open OWA inside our web application to make clients more related with the application and let them easy access their emails while working. After some researches i found a simple way to do that, actually it is not that much hard to find the code below, but you have to search well to find it!. An here is the way that i have done that, we have a page with 2 iframes inside it. Upper frame holds the links banner and the bottom frame which holds whatever is clicked from the links banner. The work is to open OWA inside the bottom Banner. To open OWA you have to create a small JavaScript for that which will send the user name and password to be authenticated in from owaauth.dll and if everything goes fine you'll successed to open your email. The code is as below;

public partial class OpenOwaPage : System.Web.UI.Page
{
    private string userName;
    private string passWord;

    protected void Page_Load(object sender, EventArgs e)
    {

            passWord = "password";
            userName ="username";
            Response.Write(CreateOWAFrom());
            Response.Write(LoadOWAPostJS("logonForm"));

    }

    private string LoadOWAPostJS(string strFormId)
    {
        //Constructs the JS needed to post the data to Realex and returns it
        StringBuilder strScript = new StringBuilder();
        strScript.Append("<script language='javascript'>");
        strScript.Append("var ctlForm = document.forms.namedItem('{0}');");
        strScript.Append("ctlForm.username.value=\"" + userName + "\";");
        strScript.Append("ctlForm.password.value=\"" + passWord + "\";");
        strScript.Append("ctlForm.submit();");
        strScript.Append("</script>");
        return String.Format(strScript.ToString(), strFormId);

    }

    private string CreateOWAFrom()
    {
        //Constructs the Realex HTML form and returns it
        StringBuilder strForm = new StringBuilder();
        strForm.AppendLine("<form id=\"logonForm\" name=\"logonForm\" target=\"_self\" action=\"https://your_Owa_Adress/exchweb/bin/auth/owaauth.dll\" method=\"post\">");
        strForm.AppendLine("<input type=\"hidden\" name=\"destination\" value=\"https://your_Owa_Adress/exchange/\"/>");
        strForm.AppendLine("<input type=\"hidden\" name=\"flags\" value=\"0\"/>");
        strForm.AppendLine("<input type=\"hidden\" name=\"username\" id=\"username\"/>");
        strForm.AppendLine("<input type=\"hidden\" name=\"password\" id=\"password\"/>");
        strForm.AppendLine("<input type=\"hidden\" id=\"SubmitCreds\" name=\"SubmitCreds\" value=\"Connection\"/>");
        strForm.AppendLine("<input type=\"hidden\" id=\"rdoRich\" name=\"forcedownlevel\" value=\"0\"/>");
        strForm.AppendLine("<input type=\"hidden\" id=\"rdoPublic\" name=\"trusted\" value=\"0\"/>");
        strForm.AppendLine("</form>");
        return strForm.ToString();

    }
}
Sometimes you maybe not able to access your OWA because of your Browser configuration, add your OWA website address to your Browser trusted site to solve this problem. If you do not want to logoff from OWA with the regular logoff button, read this (click here). Otherwise you'll enter OWA any time you type OWA address.

Hope This Helps
