Delivery Restrictions in Exchange 2003

Posted on 2009-04-28
Last Modified: 2012-06-22
We have a couple users in our advertising department that receive emails that are larger than our default Exchange limit of 10MB.  I thought by changing their AD accounts (delivery restrictions) to not use the default limit I could control this.  But emails are still being rejected by our Exchange server if they are over the 10MB limit.  What am I missing?  We are running Exchange 2003.  Thanks!

    Per-user configuration for (SubmissionContLength) does not override connector defined limits.


    Hope this helps!!

    Just to clarify, you have adjusted each of the specified users' AD accounts through the DC server AD Users and Computers system. Right-clicking on each user, going to Properties and the Exchange General tab. You set Delivery Restrictions for Receiving message size to a Maximum KB of a number larger than 10000.

    Also check the maximum size on the Default SMTP Virtual Server in Exchange System Manager:

    Servers  + <SERVERNAME> + Protocols + SMTP + Default SMTP + Properties.
    Click  Messages tab and adjust the settings as you need.

    Assuming that you don't want to change it for the entire organization, you won't want to change the Global settings:

    Global  Settings + Message Delivery + Properties. Defaults  tab and set the Receiving Message size

    I dont want to change the Global Setting for all users.  This is something I need to change for only a couple users.  There is not a limit set in the SMTP virtual server properties.  Im guess this is not possible unless you change the Global Setting?

    Assisted Solution

    The difficulty for the system is that it uses the most restrictive policy to determine the limits for individuals. If your Global setting is the most restrictive, it obviously limits everyone. If the Global is less-restrictive, then you have to use other methods to restrict the size. This article has a good explanation of the options for message limits.
    One relatively easy way for you to increase the message size limits for a small group is to start by changing the masses' size limits Globally. Then, use the ADModify application to manually change whichever OUs to a lower restriction, just don't add the Advertising OU.
