      When I was developing my windows app and specified the SMTP server in code I would get the 'Cannot access CDO message objet'. I found some online docs that said to use the smart host property in IIS SMTP virtual server. My app worked fine and still does for all users except one. Now that user is getting "the 'Send Using' Configuration value is invalid" exception. Have you heard of other resons for this exception being thrown and how to handle it? Thanks!

    I have set the SmtpServer property to localhost, 127.0.0.1 and even the ip address my dsl provider gave to this machine but couldn't get rid of this error.

      I ran into the same thing you did. I tried setting the configuration properties, and got the error you did. If I removed the configuration stuff, I went back to the original "SendUsing" configuration value error.
      
      Luckily, I stumbled upon a fix. I was moving a site from one Win2k3 server to another. It worked on the old one, but wasn't working on the new one. After comparing the SMTP settings between the two, I found a difference. When I set them up identically, the problem went away, without needing the configuration code.
      
      Here's what I did:
      
      * Go to the Internet Information Services manager, and right-click on Default SMTP Virtual Server; select Properties. This will give you a pop-up titled "Default SMTP Virtual Server Properties."
      * Go to the Security tab, and look at the list of operators. My working configuration has three entries:
      
      - Administrators (the machine's local group)
      - NT AUTHORITY\LOCAL SERVICE
      - NT AUTHORITY\NETWORK SERVICE
      
      If you don't have those last two lines, you will continue to get the error, regardless of what you do programmatically.
      
      To add the last two:
      * Hit the Add button; you will get a pop-up titled "Select Users or Groups."
      * Hit the Object Types button; you will get a pop-up titled "Object Types." Make sure Users, Groups and Security Principals are checked, then hit OK. This takes you back to the "Select Users or Groups" pop-up.
      * Hit the Locations button; this will give you a pop-up titled "Locations." Select the machine name (not a domain) from the list, then hit OK. This will take you back to "Select Users or Groups."
      * Hit the Advanced button; this will bring up another, larger pop-up titled "Select Users or Groups."
      * In this new pop-up window, hit Find Now. It will show you a complete list of users, groups and internal security principals for the machine
      * Select LOCAL SERVICE and NETWORK SERVICE, then hit OK
      * You're back to the smaller "Select Users or Groups" pop-up. You should see LOCAL SERVICE and NETWORK SERVICE in the box. Hit OK
      * You're now back to the "Default SMTP Virtual Server Properties" window. You should now have all the necessary groups listed.
      
      After doing this, I was able to get ASP to send e-mail from that server, without needing to mess with any SmtpMail.* stuff, at all.

    • RE RE: Help    [ Reply ]

      Step 1
      Use SmtpMail.SmtpServer = "localhost" in your code to get rid of This error: The "SendUsing" configuration value is invalid.
      
      Step 2
      Run inetmgr, then right click on "Default SMTP Virtual Server", then choose the Tab "Access", then click on "Relay..." button from "Relay restrictions", then choose "All except the list below" radio button and click OK.
      This will get rid of the relay error.
      
      Have to follow both Step 1 and Step 2.
      
      Thanks for all the help from this website and replies from everybody

        After you set the "SmtpMail.SmtpServer" settings, make sure you set the Application Protection settings to low in IIS ( under IIS --> properties--> home directory )
        This worked on Win XP Pro SP 2.

• Help with EMail Feedback form    [ Reply ]

  Hi everybody,
  I have a feedback form to send an email message form my web site:
  the code is below:
  
  private void SendMail()
  {
  MailMessage objEmail = new MailMessage();
  objEmail.From= "abcl@abc.com";
  objEMail.To = "aaa@aaa.ca";
  
  ...other parameters
  SmtpMail.SmtpServer = "smtp.whatever.ca";
  SmtpMail.Send( objEMail);
  objEmail = null;
  }
  
  if I use it with my ISP (with local smtp and local mailboxes)on my IIS everything is fine I can send the form
  without any problem. When I upload it to my host service (obviously
  modifying accordingly to the provided SMTP) ,an exception get thrown. The Hosting Service claims that is my code , but I cannot find anything
  wrong with it.( considering that works with my IIS).but I don't like to say
  that they are wrong until I am positive that I am not.
  
  Can anybody help me please and give me more information on how to solve this
  problem?
  
  
  thank you in advance for your help

    Sorry:
    To clarify the previous , the exception is:
    By debuggin it from the visual studio environment:
    ex.Message = "Could not access CDO.Message object"
    
    when I actually upload to the host, with
    <customErrors

  Is it possible to bypass the local smtp server (running with IIS) and send directly to our in-house smtp gateway machine?
  
  Currently we're using the smarthost setting to route to gateway, but wondered if we could eliminate this and code directly. If not, is this feature available in 3rd party products?
  Thanks

    This is a very good example of why reading solutions to code problems is so frustrating.
    
    SmtpMail.SmtpServer = "mail.your-domain.com"
    where is this statement supposed to be written?
    In web.config? On a code behind page? I need the context of where this statement should be.
    
    Then it says " if you are using the local SMTP...." Are you talking about the ISP as the local? or are you talking about on my own computer where I am creating the code?
    
    127.0.0.1 - Will this physical address work on my ISP or are you trying to say I should use the ISP's physical address?
    
    The machine name here. Is this my ISP's machine name?
    
    The real dns name here. What does dns stand for?
    
    The machine IP Address here. Is this the ISP address? If so why the 127.0.0.1 address?
    
    It is very frustrating to constantly see how to do something and not understand what they mean.

  • RE: The "SendUsing" configuration value is invalid.    [ Reply ]

    The "SendUsing" configuration value is invalid.
    Typically this exception has to deal with the following line of code (or I should say ABSENCE of the following line of code):
    
    SmtpMail.SmtpServer = "mail.your-domain.com"
    By default, if SmtpMail.SmtpServer is not set, System.Web.Mail is supposed to use localhost as the default property. However, for some reason this doesn't appear work. If you are using the local SMTP Service to send emails, you may try the following values:
    "127.0.0.1"
    "localhost"
    "the_machine_name_here"
    "the_real_dns_name_here"
    "the_machine_IP_Address_here"
    That should fix it.

• 4.2.10 "Could not access 'CDO.Message' Object - Part 8    [ Reply ]

  I got the error "Could not access 'CDO.Message' Object" with the inner exception being "The "SendUsing" configuration value is invalid." when I used System.Web.Mail to send emails through a VB.NET program which was running under a non-administrator ID. One solution is to add the ID to the administrators group which unfortunately is not a very secure solution :)
  
  I tried all the solutions suggested in this FAQ, but the solution that finally worked for me is as follows -
  
  Add the following 2 lines in your code: (assuming oMessage is your object of type System.Web.Mail.MailMessage)
  
  oMessage.Fields("http://schemas.microsoft.com/cdo/configuration/sendusing";) = 1
  oMessage.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserverpickupdirectory";) = "C:\\Inetpub\\mailroot\\Pickup"
  
  And also grant write access to your pickup directory ("C:\\Inetpub\\mailroot\\Pickup" in this example) to the ID this program is running as.
  
  The reason is that if your program is running under a non-administrative ID, it does not have access to be able to identify what the SMTP pickup directory is. So if you specify that explicitly in your code, everything runs fine. Ofcourse you can then read the value from your config file and remove the hard-coding. You can look at http://support.microsoft.com/kb/816789 for more details on why this access is lost however their solution didn't work for me.
  
  I got this solution working after a couple of days of frustrating "permissions-changing" here and there, so hope this works for you and you save your 2 days :)

  Have it set to a valid mail server. Test using it with other apps, but .net still throws this error, and all innerexception say the same thing. Any ideas out there?

• working with CDOSYS    [ Reply ]

  My host's server does not support SmtpMail, but they do support the underlying CDO.. not sure why, but I'm getting this
  
  System.Runtime.InteropServices.COMException: The "SendUsing" configuration value is invalid.
  
  Here's my code:
  
  using CDO;
  using ADODB;
  
  Message MyMessage = new MessageClass();
  MyMessage.HTMLBody = "some HTML";
  MyMessage.From = "a name";
  MyMessage.To = "an email address";
  MyMessage.Subject = "a subject";
  MyMessage.Send();
  
  I got the ADODB from another forum that had an example.. they used the ConfigurationClass() to set 'field' values in the MessageClass() object, but it was specific to their purpose and I can't find any documentation on CDOSYS to tell me what the general parameters are. And no, I can't find any SmtpServer property, or any "server" property at all inside CDO.
  
  Any help greatly appreciated. Thanks in advance.

  • RE: working with CDOSYS    [ Reply ]

    This will work, from what I know, with Exchange Server 2000 SP3, as long as you've added xxx.mailserver.com to the IIS Smart Host configuration.
    
    Public Function sendtextmail (mailto,mailfrom,mailsubject,mailtext)
    Dim iMsg
    Dim iConf
    Dim Flds
    Const cdoSendUsingPort = 2
    Const strSmartHost = "xxx.mailserver.com"
    
    'Create the message object.
    Set iMsg = CreateObject("CDO.Message")
    
    'Create the configuration object.
    Set iConf = iMsg.Configuration
    
    'Set the fields of the configuration object to send by using SMTP through port 25.
    With iConf.Fields
    .item("http://schemas.microsoft.com/cdo/configuration/sendusing";) = cdoSendUsingPort
    .item("http://schemas.microsoft.com/cdo/configuration/smtpserver";) = strSmartHost
    .Update
    End With
    
    'Set the To, From, Subject, and Body properties of the message.
    With iMsg
    .To = mailto
    .From = mailfrom
    .Subject = mailsubject
    .TextBody = mailtext
    .Send
    End With
    
    set iMsg = Nothing
    End Function

• System.web.mail.STMPmail    [ Reply ]

  Hi there,If i use System.web.mail.STMPmail to send a message to multiple addresses, and if it fails to send the message to one or tow recipents, then does it fail to send to other addresses as well? if yes then what would be the reason for that? is it going to send the message to the Cc, Bcc addresses too or its just gonna die or fail.

  • RE: System.web.mail.STMPmail    [ Reply ]

    if u deal with the local machine as a server and build a web application to send message to ur machine from the ur application
    then
    smtpMail.smtpServer = "machineName."
    where machine name is ur computer name from My computer>right_click properties>computer name [ then copy and past ] .
    
    but if u send it to another server like yahoo :
    u must specify the smtpServer of the yahoo like
    smtpMail.smtpServer = "mx.mail.yahoo.com"
    
    as "mx.mail.yahoo.com" is the yahoo real mail server address.
    and
    hope i help

• MailFormat.Html    [ Reply ]

  Here's a new one for you...any answers for this? When I set MailFormat to Html n my XP box and try to send to my mail server, I get the narly 'CDO Access...' error. When I keep everything the same and simply change the MailFormat to Text....it works perfect. Any ideas what this could be? Is this permissions on a temp directory or something like another workaround was?
  
  Thanks...

• Another reason to receive this error code    [ Reply ]

  I had a user who was receiving this error clicking button in an excel file. The debugger went to a line in the script with just this on it: ".Send". It works on every other users machine. Long story short .. IIS was not installed.

• CDO Fix for exception    [ Reply ]

  If you've installed .NET prior to installing the SMTP service then make sure that you give ASPNET modify permissions over C:\Documents and Settings\All Users\Application Data\Microsoft and all its subdirectories. It looks like ASPNET needs to create itself and RSA machine key files before it can send anything.

• Send Using config value is invalid    [ Reply ]

  I'm getting this error when I run my mail service on Win server 2008 - fine on XP & 2003. I'm sending the mail to a server on the net (NOT a local exchange server) & its set to "cdoSendUsingPort" i.e. "2" which I think is correct. Is it a rights issue ( as I've had loads of them with 2008) or what?
