Outlook 2003 delivers large messeges to Exchange, even if there is a 20 MB limit set

I am administering an Exchange 2003 on Windows 2000 server.

There is a problem with our local users. If a user is sending let's say
an 100 MB attachement, even if we activated de Global settings, Message delivery, Defaults, Sending message size to maximum 30000 KB,
MS Outlook is SENDING the message to the server and places it in Sent Items.

The server sends an NDR message, attaches the mail and so... the users mailbox exceeds the size of 200 mb (set as maximum by us)
and the server stops sending any new messages to anyone.

we have to restart the server and loose many undelivered messages.

If I set the limit in the Smtp connector, do you think that the server will accept the mail and return to the Outlook client?
Or just refuses the mail and do not transfer it?

    Restarting the server should not lose any undelivered messages, so you have a problem there to begin with.

    For the size restriction issue, I would suggest that you start by reviewing this article on Technet:
    It explains how the restrictions are applied to email messages.

    If you are setting the limit on the SMTP transport then the message will be sent to Exchange by Outlook, as the restriction is taking place later.

    I read the article.

    I have Global Setting, Message Delivery, Sending Message Size, Maximum (KB) set to 30000

    Default SMTP Virtual Server settings Messages (limit message size and limit session size) unchecked.

    I set in AD my account, Exchange General, Sending message size, Maximum KB at 1000.

    I consider that me and all the users should not be able to submint messages to the Exchange with attachements larger than (1 000 and 30 000). But the messages are delivered to the server and eventually results an NDR.
    What else should I check?

    Still looking for an answer, increased point value.
    Should the Trend Micro Scan Mail for Exchange Server affect this?

    Unfortunately this site doesn't work like a forum. You can increase the points as much as you like, it will not get anyone else to look as the question is no longer on the first page and you cannot bump the question to get it on the top of the list.

    The most that you can do is post a pointer question (minimum points) that points to this question.

    To answer your question - anything third party could be causing a problem and should be removed to prove it is not the source of the problem.

    I discovered that it is working fine if Outlook is not cached.

    Simon, Thanks for the tips on using the site.
