I have written a small page that is supposed to email an excel spreadsheet when a button is clicked. The page works fine on my system, which is XP Pro. But when I copy it to the server, it fails. The server is a Windows 2003 SB Server which has Exchange Server 2003. I verified that the SMTP server is up and running. I am really stumper as to why it won't work on the server. There is no error. I just performed a Try/Catch and setup a label to let me know if it worked or not. Here is the code I am using, any help that could be provided would be appreciated.<BR><BR>Thanks,<BR><BR>Try<BR>Dim objMailMessage As Mail.MailMessage<BR>Dim objMailAttachment = New Mail.MailAttachment("c:TTE_Assignment_Billing.xls" )<BR><BR>objMailMessage = New Mail.MailMessage<BR>objMailMessage.From = hidden for security reasons<BR>objMailMessage.To = hidden for security reasons<BR>objMailMessage.Bcc = hidden for security reasons<BR>objMailMessage.Subject = "Your spreadsheet is attached to this email."<BR>objMailMessage.Body = "Please check the attachment for the spreadsheet."<BR>objMailMessage.Attachments.Add(ob jMailAttachment)<BR><BR><BR>Mail.SmtpMail.Send(obj MailMessage)<BR><BR>lblEmail.Text = "The email has been sent successfully!"<BR><BR>Catch ex As Exception<BR><BR>lblEmail.Text = "The email was not sent successfully!"
