How to Change the Default Message Delivery Options

  • Article

 

  • This procedure outlines how you can modify the default message delivery options. Exchange applies the settings for these options globally to all users. However, you can override these settings on a per-user basis in Active Directory Users and Computers. For information about how to override these settings, see Managing Recipients and Recipient Policies in Exchange Server 2003.

Procedure

To change the default message delivery options

  • In the Message Delivery Properties dialog box, on the Defaults tab (see the following figure), select the appropriate options.

The maximum message size that can be sent by users This is the Sending message size option, and it defaults to 10240 KB (users can send a message of any size). Based on your available network bandwidth and your user requirements, you may want to limit the maximum message size that is allowed in your organization. If a user tries to send a message that exceeds the specified size limit, the user receives a non-delivery report (NDR) and Exchange will not send the message.

The maximum message size that can be received by users This is the Receiving message size option, and it defaults to 10240 KB (users can receive a message of any size). Again, based on network bandwidth and user requirements, you may want to limit the message size. Senders in your organization receive an NDR if they try to send a message to a user who exceeds the specified size limit. Depending on the NDR settings that you configure in Internet Message Formats, external senders may or may not receive an NDR.

The maximum number of recipients to which a single message can be sent This is the Recipient limits option, and it defaults to 5000 recipients. Recipients include all users on the To, Cc, and Bcc lines, and also expanded distribution lists. Select No limit to allow users to send and receive messages regardless of how many recipients to which the messages are addressed.
