"Could not access 'CDO.Message' Object

This suggestion comes compliments of mkayuri.

Thanks!

---------------------------------- Appreciate your great work on this error.
I thought I tried everything on this site, kept changing this and that and this and that...
When I used local smtp relay service, it works fine, but my case sends e-mail to the outside SMTP server (instead of localhost SMTP relay service) with SMTP Authentication;
I solved mine with adding the timeout setting;
MailMessage msg = new MailMessage();
...
msg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout", 60);

The default value for smtp connection timeout is 30seconds. I just beefed up that part. I guess, 30 seconds wasn't enough for all SMTP connection (incl. name resolution, user authentication, etc. ).

I've been reading all small prints on this site and contemplating. But, somehow I got this solution so I wanted to say thank you and here's my due. :-)

I hope this might help someone else!

Could not access CDO.Message [ Reply ]
When the email server goes down, I also get this kind error message. Is there a way to queue the message so that when the system is back up, it can be sent out at that time.

When we use the Outlook, it queues the message when the system is down.

Thanks!

Could not access 'CDO.Message' Object - Part 9 [ Reply ]
This tip is for the absolute beginners.. I just wasted too much time working it out:

Initally I was including the Mail Namespace as per:
<%@ Import Namespace="System.Web.Mail" %>
.....
Instead of the following:

<%@ Import Namespace="System" %>
<%@ Import Namespace="System.Web" %>
<%@ Import Namespace="System.Web.Mail" %>
<script runat="server">

Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

Dim mail As New MailMessage()
mail.To = "postmaster@blah.com"
mail.From = "postmaster@blah.com"
mail.Subject = "Registration"
mail.BodyFormat = MailFormat.Html
mail.BodyFormat = MailFormat.Text
mail.Body = "This is a test"

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate";, "1")
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername";, "postmaster@blah.com")
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword";, "blah")

System.Web.Mail.SmtpMail.SmtpServer= "mail.blah.com"
System.Web.Mail.SmtpMail.Send(mail)

End sub

The same applies for c#

Really simple stuff but it caught me out. Good luck if your struggling.

  Hi, I've been trying to work around this error for couple of days:-(
  
  My magical solution was to add this:
  (C#)
  msg.Priority = MailPriority.Normal;
  
  It seems like that the SMTP Mail Server has default priority set at High. I've tried all other suggestions in this FAQ (and more) and finally decided to try this line after reading in one of the FAQ's about deleting a line setting MailPriority.High or to change it to MailPriority.Normal. Since I did not set the priority before and added this line I've concluded that my SMTP server must have priority set default to High!! But I've been unable to find out if that was the case. Just happy this is working now:-)

Could not access 'CDO.Message' Object - Part 9 [ Reply ]
At our company, we use the corporate edition of McAfee VirusScan, which blocks TCP Port 25.

Here is a VB.NET workaround that I just devised. Still working on a way to prevent the command prompt NET.EXE windows from appearing:

Sub Main()

sendEMail()

Console.WriteLine(vbCrLf & "Press a key to exit.")
Console.ReadLine()

End Sub

Private Sub stopMcAfee()

Dim proc As Process

proc = Process.Start("NET.EXE", "STOP McAfeeFramework")
proc.WaitForExit()

proc = Process.Start("NET.EXE", "STOP McShield")
proc.WaitForExit()

proc = Process.Start("NET.EXE", "STOP McTaskManager")
proc.WaitForExit()

End Sub

Private Sub startMcAfee()

Dim proc As Process

proc = Process.Start("NET.EXE", "START McAfeeFramework")
proc.WaitForExit()

proc = Process.Start("NET.EXE", "START McShield")
proc.WaitForExit()

proc = Process.Start("NET.EXE", "START McTaskManager")
proc.WaitForExit()

End Sub

Private Sub sendEMail()

Dim mail As New MailMessage()
Dim from As String = "legitimate.account@someplace.com"
Dim subject As String = "Test Subject"
Dim body As String = _
"<html><body><h1>Test Body</h1><hr><p>Message Content</p></body></html>"

SmtpMail.SmtpServer = "yoursmtpserver@yourcompany.com"

With mail
.From = from
.Subject = subject
.BodyFormat = MailFormat.Html
.Body = body
.To = "youremailaddress@yourcompany.com"
End With

Try
Console.WriteLine("Stopping McAfee Services...")
stopMcAfee()

Console.WriteLine("Sending Email...")
SmtpMail.Send(mail)

Console.WriteLine("Starting McAfee Services...")
startMcAfee()

Catch exc As HttpException
Console.WriteLine(exc.Message)
Console.WriteLine(exc.InnerException.Message)
Console.WriteLine(exc.InnerException.InnerException.Message)
End Try

End Sub

  I did some modifications in Virus scan.
  Right click on virus scan and go to Virus scan console.
  Again in the open window right click on Access Protection and click properties.
  In Port Blocking select Prevent mass mailing worms from sending email and say EDIT.In that EXCLUDED PROCESSES add the exe file and save the properties.
  It should help and you should be able to send email.

CDO message errors [ Reply ]
I think, all are leading to a wrong way. Have yo u ever checked that you have CDO DLL installed on your machine.I recently removed MS OUTLOOK 2003 and that stopped me from using SMTP server in VB.NET.

Hope this helps.

If that doesn't help I removed a wscript sleep 1000 command and that seems to have helped!

Could not access'CDO.MESSAGE' [ Reply ]
I have several .net 2000 client servier applications that worked fine until our agency policy was to remove adminitrative rights from users machines. Once this was done this error occurred. I have admin rights on all machines so I tried logging on under me, setting STMP and when the user logged in it doesn't work. I tried everything possible that I could think of and nothing worked. Can anyone help?

I added the code which displays errors in more detail. The error I got was "SendUsing" configuration value is invalid.

  If I had to guess, you don't have the correct permissions on the registry keys to create the CDO objects.
  
  I would use something like Regmon to see if you are getting any access denied errors from the registry.
  
  Cheers!
