DOCUMENT:Q192052 25-APR-1999 [exchange] TITLE :XFOR: MSMI: Messages with Incomplete X.400 Addresses are NDR PRODUCT :Microsoft Exchange PROD/VER:WinNT:5.5 OPER/SYS: KEYWORDS:exc55sp2fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.5 ------------------------------------------------------------------------------- SYMPTOMS ======== Messages sent from a foreign system to an MS Mail user via the MS Mail Connector of an Exchange Server computer are not valid address types for reply when they are received at the MS Mail postoffice. Foreign address types are any address type that the MS Mail postoffice does not have a gateway or access component installed for routing. CAUSE ===== When the MS Mail Connector receives a message with a foreign address type, it will convert the address to an X.400 address with DDA (domain defined attribute) type and DDA value. The problem is that the X.400 address does not include the GDI (Global Domain Identifier) from the Exchange Server computer. When a client replies to the address, the MS Mail Connector will generate an non-delivery report back to the client as a non-routable address. RESOLUTION ========== To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base: Q191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack STATUS ====== Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5. ====================================================================== Keywords : exc55sp2fix Technology : kbExchangeSearch kbExchange550 kbZNotKeyword2 Version : WinNT:5.5 Issue type : kbbug Solution Type : kbfix ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
