Hi

 I have the below Web method in my Web service. It works fine when i debug it in Visual studio. But when i create a Web set up project and install in on the server it gives an error.

    [WebMethod]
        public string WebServiceTest()
        {
            try
            {
                Microsoft.Office.Interop.Outlook.Application oOutlook;
                oOutlook = new Microsoft.Office.Interop.Outlook.Application(); //error
                return "1";
            }
            catch (System.Exception ex)
            {
                return ex.ToString();
            }
          
        }

 The exception is System.UnauthorizedAccessException}

Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80070005."} System.SystemException {System.UnauthorizedAccessException}

 How to set permissions to launch Outlook from a web application or web service?

Thanks
