Unable to Send Private Message to Exchange Recipient

• Microsoft Exchange Server, versions 5.0 and 5.5

SYMPTOMS

When you try to send a private message to a Microsoft Exchange Server recipient who has a designated alternate recipient, you may receive the following non-delivery report (NDR):

   From: System Administrator
   Subject: Undeliverable: test message

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

      Subject: test message
      Sent: 12/1/97 12:00 PM

   The following recipient(s) could not be reached:

      John Doe on 12/1/97 12:00 PM

      Unable to deliver the message because the originator prohibited
      redirection to an alternate recipient or the message was encrypted

      MSEXCH:MSExchangeMTA:<SiteName>:<ServerName>

CAUSE

This is by design. Private messages sent to a specific recipient are not intended to be received by an alternate recipient.

WORKAROUND

To prevent this behavior, disable the use of alternate recipients on the mailbox. Alternate recipients are designated in the Microsoft Exchange Administrator program by selecting the Delivery Options tab of the recipient's mailbox.

In Microsoft Outlook, you can assign delegate permissions for your mailbox to other users. This enables private messages to be delivered to your mailbox, but delegates cannot view these private messages.
