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.



Exchange Server 5.0
A supported fix that corrects this problem is now available from Microsoft, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Microsoft Exchange Server 5.0 service pack that contains this fix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information on support costs, please go to the following address on the World Wide Web:

Exchange Server 5.5

Microsoft has confirmed this to be a problem in Microsoft Exchange Server versions 5.0 and 5.5.
