    I would like to send mails using MS Exchange from ASP.NET application. Is it
    possible to achieve this with CDO 1.21? Currently I'm using Redemption
    (version 4.2) and I have the following problem: E-mails can only be send
    when Outlook is opened on the computer where IIS is working. If Outlook is
    closed, every logon method call shows dialog with username, server name and
    password (although I have entered correct user profile name and password).
    Is it possible to disable this dialog? How to login with no dialog? The main
    problem is that I would like to login to different accounts.... How to
    achieve this?

    When I was trying to add reference to CDO 1.21 to my VS Express project an
    error has occured. I've read on forum that it is impossible to use cdo with
    ASP.NET? Is this true? If it is possible how to do it?

    I would recommend using WebDav, you will not get a reliable solution using

    You can hand code the webdav calls, or use a third party product.

    I used this wrapper and it save me a lot of time. It lets you send email
    from exchange, read inboxes, public folders, etc.

    Well, I've tried this possibility too, but the problem is that solution
    doesnt't work...... When I'm preparing HttpWebResponse and calling
    request.GetResponse() I've got an Exception (error 501: Not Implemented).
    Maybe the problem is that I'm using Exchange 5.5? If any code examples or
    ideas it would be nice.....
    Thanks, I will try it.

    I have to ask the question: Why not use System.Net.Mail? You can
    connect to Exchange and send mails from ASP.NET pages very easily
    without needing additional credentials (system credentials are

    I believe CDO is somewhat deprecated and not encouraged to be used any
    longer... So going forward, if you choose to use CDO, you may find it
    difficult to support or maintain...

    I don't know what your requirements are, so I understand that you may
    *have* to use CDO, but wasn't sure if you've considered it...
