CAUSE

This issue occurs because Outlook 2003 does not prevent files that would cause a message to exceed maximum size limits from being attached to messages. When Outlook 2003 is running in online mode, Outlook 2003 sends the data in the attachment to the Exchange Server 2003 server or to the Exchange 2000 Server server even though the attachment exceeds message size limits that are configured on the server.

MORE INFORMATION

This hotfix adds functionality that enables Outlook 2003 to examine the size of attachments when a user adds an attachment to a message. This functionality is implemented by using a counter that tracks the total size of attachments that are added to a message in Outlook 2003.

When a user tries to add an attachment to a message, Outlook 2003 checks to see whether the size of the attachment that was added to the current value of the counter exceeds the maximum size limit for messages. If the size of the attachment that was added to the current value of the counter exceeds the maximum size limit, the attachment is not added to the message. Additionally, the user receives a message to notify them that the attachment will not be added to the message.

Notes

The counter is reset if attachments are removed from the message.
The counter only tracks the size of file attachments. It does not track embedded messages because the size of embedded messages may change.
