SYMPTOMS
When you try to replicate public folders from a domain that has a Microsoft Exchange Server 5.5 computer or a Microsoft Exchange 2000 Server computer to a domain that has a Microsoft Exchange Server 2003 computer, you receive the following non-delivery report (NDR) message:

General access denied, sender access denied—The sender of the message does not have the privileges necessary to complete delivery.



CAUSE
This issue occurs because all public folder replication that uses Simple Mail Transfer Protocol (SMTP) must originate from an authenticated source or from a server that has been granted Send As permissions.



MORE INFORMATION
To verify that you have this issue, you can set diagnostic logging in the Exchange Transport Categorizer to the maximum setting on the Exchange 2003 computer.

To configure diagnostic logging on the Exchange 2003 server, follow these steps:
 * 1) Start Exchange System Manager.
 * 2) Expand Administrative Groups, expand First Administrative Group, and then expand Server.
 * 3) Right-click the Exchange Server that is listed under Servers, and then click Properties.
 * 4) Click the Diagnostics Logging tab, and then click to select the MSExchangeTransport box under the Services box.
 * 5) Under the Categories box, click the Categorizer box.
 * 6) Under Logging level, click Maximum.
 * 7) Click OK.
 * 8) Quit Exchange System Manager.

Both of the following events are logged in the application event log:

Event 1

Event Category: Categorizer

WORKAROUND
To work around this issue, edit the registry on your Exchange 2003 computer, and add a new key to the MSExchangeTransport key.

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.

To edit the registry and add a new key to the MSExchangeTransport key, follow these steps:  Click Start, click Run, type regedit, and then click OK. Expand the following registry key:

 Right-click, point to New, and then click Key.
