If you enable this option, you can save server and network resources. However, there are drawbacks to this implementation of Simple Mail Transfer Protocol (SMTP) attachment stripping. If you enable this option to strip the attachments from the non-delivery report (NDR), the details that are necessary to display the notification in the preview pane are also stripped, and the originator of the message cannot use the Send Again option. If the originator of the message tries to use the Send Again option from the NDR, the originator of the message receives the following error message:
However, the originator of the message cannot resend the message, even by using the method in the error message.
Unable to resend the message. The nondelivery report does not contain sufficient information about the original message. To resend the message, open it in your Sent Items folder, click the Actions menu, and click "Resend this message".
To enable this option, you need to edit the registry.
