SYMPTOMS
In Exchange 2003, the e-mail message body of incoming Message Disposition Notification (MDN) receipts may be replaced with a standard text. MDN receipts are read receipt and non-read receipts. The standard text appears similar to the following:

Your message

To: User@Domain.com

was read on DateandTime



CAUSE
This problem may occur when Exchange processes a MDN receipt as a report instead of as a message.



RESOLUTION
To resolve this problem, obtain the latest service pack for Microsoft Exchange Server 2003. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

836993 How to obtain the latest service packs for Exchange Server 2003

Turn on the RenderMDNsAsMessages registry value
After you install Exchange Server 2003 SP1, you can then turn on the RenderMDNsAsMessages registry value on your Exchange server. After this registry value is turned on, subsequent MDN receipts are processed using the standard e-mail message format of IPM.note.

Note By default, this setting is turned off and will use the report format that replaces the e-mail message body with the standard MDN receipt text.

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.  Click Start, click Run, type regedt32, and then click OK. Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem\InternetContent

 Click RenderMDNsAsMessages, and then on the Edit menu, click Modify. Type 1, and then click OK. Quit Registry Editor.</ol>

MORE INFORMATION
In Exchange 2003, the e-mail message body of the MDN receipt is changed because multipart/report messages are converted to the corresponding MAPI reports. The available MAPI reports include read receipts, non-read receipts, delivery receipts, and non-delivery receipts.
