SYMPTOMS

If an application posts a message to the user's outbox during the time the application is synchronizing the user's outbox, the MAPI spooler sends a non-delivery report (NDR) on this newly submitted message with the following error message:

   Your message did not reach some or all of the intended recipients.

      Subject: Extended MAPI message 11001.
      Sent: 11/24/97 4:44:59 PM

   The following recipient(s) could not be reached:

      <RECIPIENT NAME>
      No transport provider was available for delivery to this recipient.
