Question:<\/span><\/p>\n

On an application based in CDO<\/span>-Collaboration Data Objects (tool developed by Microsoft to make it easier sending messages in applications)-, the IIS <\/span>– Internet Information Services – is used to send e-mails without using the SendMail <\/span>driver.<\/p>\n

However, the messages are not being sent, and an error message is returned. How can I fix this problem?<\/p>\n

Solution: <\/span><\/p>\n<\/div>\n

This can happen because the server being used needs authentication. So, to fix the problem, you must increment the following lines in the script that sends the e-mail:<\/div>\n
Sub CommandButton1_Click() <\/span>
Set objMessage = CreateObject(\"CDO.Message\")<\/span>
objMessage.Subject = \"Email's title\"<\/span>
objMessage.Sender = \"sender@server.com\"<\/span>
objMessage.To = \"recipient@server.com\"<\/span>
objMessage.TextBody = \"Email's text body\"<\/span>
objMessage.Configuration.Fields.Item(\"http:\/\/schemas.microsoft.com\/cdo\/configuration\/sendusing\") = 2<\/span>
objMessage.Configuration.Fields.Item(\"http:\/\/schemas.microsoft.com\/cdo\/configuration\/smtpserver\") = \"smtp.server.com\"<\/span>
objMessage.Configuration.Fields.Item(\"http:\/\/schemas.microsoft.com\/cdo\/configuration\/smtpserverport\") = 465<\/span>
objMessage.Configuration.Fields.Item(\"http:\/\/schemas.microsoft.com\/cdo\/configuration\/smtpauthenticate\") = 1<\/span>
objMessage.Configuration.Fields.Item(\"http:\/\/schemas.microsoft.com\/cdo\/configuration\/sendusername\") = \"send@server.com\"<\/span>
objMessage.Configuration.Fields.Item(\"http:\/\/schemas.microsoft.com\/cdo\/configuration\/sendpassword\") = \"user password\"<\/span>
objMessage.Configuration.Fields.Item(\"http:\/\/schemas.microsoft.com\/cdo\/configuration\/smtpusessl\") = true<\/span>
objMessage.Configuration.Fields.Item(\"http:\/\/schemas.microsoft.com\/cdo\/configuration\/smtpconnectiontimeout\") = 60<\/span>
objMessage.Configuration.Fields.Update<\/span>
objMessage.Send<\/span>
MsgBox \"The e-mail was successfully sent!\"<\/span>
End Sub<\/span>
\r\n<\/pre>\n
Limitations of CDO in Modern Providers<\/strong><\/p>\n
CDO (Collaboration Data Objects) is a legacy Windows component that uses an outdated TLS implementation for secure communication with SMTP servers. Providers such as Gmail, Outlook\/Hotmail, and Yahoo have discontinued support for TLS 1.0 and TLS 1.1, currently accepting only TLS 1.2 or higher. Since CDO has limited and unstable support for TLS 1.2, making it incompatible with most modern email providers, send attempts through these providers result in errors such as:<\/p>\n
    \n
  • 0x80040217<\/strong> \u2014 Server not available<\/li>\n
  • 0x80040213<\/strong> \u2014 Transport connection failed<\/li>\n
  • 8004020E<\/strong> \u2014 Sender rejected by server<\/li>\n<\/ul>\n
    Alternative: Sending via PowerShell<\/strong><\/p>\n
    As an alternative to CDO, it is possible to use Windows PowerShell to send e-mails directly from Elipse E3 VBScript using the WScript.Shell<\/strong> object.<\/p>\n
    Component Used<\/strong><\/p>\n
    PowerShell uses the System.Net.Mail.SmtpClient<\/strong> class from the .NET Framework, which provides native support for TLS 1.2, making it compatible with the security requirements of modern e-mail providers.<\/p>\n
    Below is an example of sending an e-mail using Elipse E3:<\/p>\n
    Dim oShell\r\nSet oShell = CreateObject(\"WScript.Shell\")\r\n\r\nDim sAssunto, sCorpo, sDestinatario, sRemetente, sSenha\r\nsRemetente    = \"sender@domain.com\"\r\nsDestinatario = \"recipient@domain.com\"\r\nsAssunto      = \"Email subject\"\r\nsCorpo        = \"Email body\"\r\nsSenha        = \"senhaapp16chars\"  \r\n\r\nDim sScript\r\nsScript = \"$smtp = New-Object System.Net.Mail.SmtpClient('smtp.gmail.com', 587);\" & _\r\n          \"$smtp.EnableSsl = $true;\" & _\r\n          \"$smtp.Credentials = New-Object System.Net.NetworkCredential('\" & sRemetente & \"', '\" & sSenha & \"');\" & _\r\n          \"$msg = New-Object System.Net.Mail.MailMessage;\" & _\r\n          \"$msg.From = '\" & sRemetente & \"';\" & _\r\n          \"$msg.To.Add('\" & sDestinatario & \"');\" & _\r\n          \"$msg.Subject = '\" & sAssunto & \"';\" & _\r\n          \"$msg.Body = '\" & sCorpo & \"';\" & _\r\n          \"$smtp.Send($msg);\"\r\n\r\noShell.Run \"powershell -NoProfile -ExecutionPolicy Bypass -Command \"\"\" & sScript & \"\"\"\", 0, True\r\n\r\nSet oShell = Nothing<\/pre>\n
