SYMPTOMS
You may receive the following non-delivery report (NDR) when you send an e-mail message from an Exchange 2000 Server computer and a Microsoft Exchange Server 5.5 computer. You may receive the following NDR immediately from your local Exchange 2000 server:
Exchange Server on 2/8/2001 9:51 AM
The e-mail address could not be found.
Perhaps the recipient moved to a different e-mail organization, or there
was a mistake in the address. Check the address and try again.
<server.com > #5.1.0
No warning or event ID messages are logged in the Application event log (unless logging is set higher than MAX). If you track the message, it shows that the message stops at the local CAT. If you verify this with an LDP dump of the user in Microsoft Windows 2000 Active Directory, and compare the dump to the Exchange Server 5.5 raw properties, everything looks good.
Check that all of the attributes are there and that the server has permissions to access them.
In the registry, if you increase the logging for all MSExchange Transport to 0x7, the following error messages are logged:

This trace is successful.
CAUSE
In Regtrace, you see the following:
pszDN: CN=Public Information Store (Server)\
DEL:41ac1b72-f2ca-4be5-8be7-31825ed2e67a,CN=Deleted
Objects,CN=Configuration,DC=com
This is why this problem occurs. When you see DEL:41ac1b72-f2ca-4be5-8be7-31825ed2e67 and the DEL: entry has a globally unique identifier (GUID) as an attribute of an object, this usually points to a server that no longer exists. In most cases, either an administrator had to remove some objects from Active Directory to finish the upgrade, and the Exchange Server 5.5 GUID reference was lost, or the administrator did not remove a server properly. The Exchange Server is
trying to use attributes that are deleted, so the server returns DscRead() failed, error = 0x80040920, which is DSC_W_LDAP_NO_SUCH_OBJECT.
RESOLUTION
To resolve this problem, obtain the latest service pack for Microsoft Exchange 2000 Server. For additional information, click the following article number to view the article in the
Microsoft Knowledge Base:
301378 XGEN: How to Obtain the Latest Exchange 2000 Server Service Pack
WORKAROUND
To work around this problem:
- Run the Exchange Server 5.5 version of the Exchange Server Administrator program against the Exchange Server 5.5 computers in the site.
- Locate the server object, click the private information store, press ALT+ENTER, and then check the Public Folder Store. It must point to a valid (existent) server or you cannot send mail to that
server.
NOTE: This problem has occurred on servers that are pointing to a valid public folder information store. If you switch the association from the current public folder store to another public information store, and then back to the original public information store, it should correct this problem.
