Event Type: Error

Event ID: 3020

Description:
A non-delivery report with a status code of 5.4.6 was generated for
recipient x-ex;/O=FUNDS INC/OU=FIRST ADMINISTRATIVE
GROUP/CN=RECIPIENTS/CN=KerrySue (Message-ID
<97A0F943BF95C14FA34...@server.toto.com>).
Cause: A forward loop was detected by the categorizer. This is a common
hosting configuration problem caused when someone uses the provisioning tool
to create a contact in one organization unit and creates a user in a
different organization user that share the same e-mail address.
Solution: Verify that you do not have a user in organizational unit and a
contact in a different organizational unit that have the same e-mail
address.

What can I do to resolve this issue.

Thanks

First you should find out if you have duplicate mail addresses in your
Windows Forest.

Open Active Directory Users and Computers on an computer with Exchange
2000/2003 administration tools.
Do a Find, against all domains.
Select Exchange Recipients from the drop down menu.
From the Advanced menu select proxy addresses or Legacy DN (I don't think
this is exposed).
Set the proxy address to "X500:/O=FUNDS INC/OU=FIRST ADMINISTRATIVE
GROUP/CN=RECIPIENTS/CN=KerrySue"
see if that results in any duplicates.

You could also try to search for mailnickname = "KerrySue" or the smtp
addresses of the user. basically you are trying to find out if you have two
objects with the same email addresses. Once you find them resolve them
correctly (remove the contact if there is a mailbox, remove the mailbox
entries from the User if they shouldn't be there).
