access denied to CDO.MessageI have developed a windows application for our client, which informs passengers thru email regarding a schedule change of flights. When i tested it at my end, using their SMTP server, the mails were being sent but when application was installed at client's place, using the same SMTP server, mails are not being sent. I'm getting an error message - System.Web.HttpException: Could not access 'CDO.Message' object. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x80040220): The "SendUsing" configuration value is invalid. My code - -----------------*******************-------------------------- SmtpMail.SmtpServer.Insert(0,["SMTP_Server_Name"]); MailMessage mailMessage = new MailMessage(); mailMessage.BodyFormat = MailFormat.Html ; mailMessage.From = fromEmailId; mailMessage.To = toEmailId; mailMessage.Subject = subject; mailMessage.Body = body; mailMessage.Headers.Add("Reply-To",reply_to); mailMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout", 60); mailMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1"); mailMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", username); mailMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", pwd); SmtpMail.Send(mailMessage); -----------------*******************-------------------------- Please help me out with this. It's urgent. Thanks and Regards, Pooja. Your first line of code looks weird. SmtpMail.SmtpServer is just a string so
I really do not know what you are trying to do. Your code results in an empty string for SmtpMail.SmtpServer, so it will try to send the mail using the local SMTP server. Change the code to: SmtpMail.SmtpServer = smtpServerName; HTH, Jakob.

Thanx for replying. Actually i'm reading SMTP Server Name from the configuration settings in the first line of my code. Just changed that line while copy pasting here. Originally it looks like - SmtpMail.SmtpServer.Insert(0,System.Configuration.ConfigurationSettings.AppSettings["SMTP_Server_Name"]); Please help me now. Thanks and Regards, Pooja.

string (hence it will use the local smtp server): SmtpMail.SmtpServer.Insert(0, System.Configuration.ConfigurationSettings.AppSettings["SMTP_Server_Name"]); Instead you should use: SmtpMail.SmtpServer = System.Configuration.ConfigurationSettings.AppSettings["SMTP_Server_Name"]; Regards, Jakob.

It's still giving the same error. Do you think that on the machine from where mail is being sent, Dafault SMTP Virtaul Server needs to be configured? Thanks and Regards, Pooja.

just guessing here. I see that you are reading the SMTP Server name from the config file. While deploying, have you changed the server name to match the production SMTP Server?

with the SMTP specifications. Even if it doesn't seem to be that I suggest to look around that for exemples the carriage returns...
