SYMPTOMS

In a mixed Microsoft Exchange Server 5.5 and Exchange 2000 Server organization, when an Exchange 2000 user sends an e-mail message to a mail-enabled Exchange Server 5.5 public folder, the Exchange 2000 user may receive a non-delivery report (NDR) that is similar to the following:
The following recipient(s) could not be reached:

The format of the e-mail address is incorrect. Check the address, look up the recipient in the Address Book, or contact the recipient

When an Exchange Server 5.5 user sends an e-mail message to the same mail-enabled Exchange Server 5.5 public folder, the mail is delivered correctly.

CAUSE

This problem can occur if the public folder has a 256-character name. Exchange Server 5.5 allows a folder name of up to 256 characters, and then adds @domain.com to the end of the name in the Simple Mail Transfer Protocol (SMTP) proxy address.

When then Active Directory Connector (ADC) replicates this address to the Active Directory, the ADC truncates everything in the primary SMTP proxy address after 256 characters because the Active Directory mail attribute has a limit of 256 characters.

Exchange 2000 allows you to create a 256-character folder name, but the Recipient Update Service truncates the public folder name to 64 characters and appends @domain.com in the SMTP proxy address.

STATUS

Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server.
