SYMPTOMS
When you try to send an e-mail message to a public folder by using the alias of the public folder in the From field, the e-mail may not be sent and a non-delivery report (NDR) that is similar to the following is created:

The following recipient(s) could not be reached:. The message reached the recipient's e-mail system, but delivery was refused. Attempt to re-send the message. If it still fails, contact your system administrator.



CAUSE
This issue occurs because of the enhanced security that is provided in Exchange 2000 Server. On Exchange Server 5.5, the From field was not verified in all scenarios, and in Exchange 2000 Server this behavior has been changed. If the account that is listed in the From field is not listed on the access control list (ACL) of the public folder, the access is determined to be anonymous.



RESOLUTION
To resolve this issue, grant the anonymous account contributor permission on the public folder.



MORE INFORMATION
The public folder has recently been rehomed from an Exchange Server 5.5 to an Exchange 2000 Server. When the public folder was homed on the Exchange Server 5.5, the e-mail message was sent without difficulty.
