XADM: Message NDR after Applying 5.5 Service Pack 1 or 5.0 post-Service Pack 2 hotfix to Store.exe

ID: Q192349

The information in this article applies to:

Microsoft Exchange Server, versions 5.0, 5.5

SYMPTOMS

After you apply Microsoft Exchange Server 5.5 Service Pack (SP) 1 or a Microsoft Exchange Server 5.0 post-SP2 hotfix to Store.exe, messages sent to users on the same information store or to users outside the site may be returned with a non-delivery report (NDR) that looks similar to the following:


   Your message did not reach some or all of the intended recipients.

   Subject: message subject
   Sent:    01/01/99 11:00AM

   The following recipient(s) could not be reached:
   User1 on 01/01/99 11:00AM
      No transport provider was available for delivery to this recipient.

Also, intersite directory replication may be affected. Because intersite directory replication is message based and must pass through the Directory Service's mailbox in the information store, the replication messages may be returned in the same manner as described above. The Directory Service mailbox will appear to have a backlog of mail when you view it through the Exchange Server Administrator's Mailbox Resources tab.

CAUSE

The information store was incorrectly parsing addresses in the routing table. This incorrect parsing results in all messages being forwarded to the MTA for delivery, and then being returned as non-deliverable. An address in the routing table similar to the following will cause this problem:


   Type        Value
   FAX         FAX:/O=SAMPLEORG/OU=SAMPLESITE;

NOTE: This is just an example. It does not mean that only FAX type addresses are affected; this can happen with any address type installed by a third-party product.
