Hi all-
Im getting the following message in the Application Event Log on our exchange server.  This message occurs when someone logs into OWA or hits active synch via OMA.  Our email server has been running fine with no issues, but this event in the viewer is driving me nuts and I cant figure out how to get rid of it.  The email server Exchange 2003 loaded on a Windows 2003 Server Domain controller.  The original exchange server 2000 is still online and an active domain controller.  The mailboxes were migrated over to the new exchange 2003 server and everything is ok.
Event ID 9549
An ambiguous SMTP proxy SystemMailbox{570699CF-552D-429B-ABDA-16A7B565AD41} was found on 0x2 mailboxes in the DS.  The store cannot map this SMTP proxy to a unique Mailbox GUID.

I did some digging around and found 2 SystemMailboxes (one with a CNF appended to the end of the character string) in ADUC  - Microsoft Exchange System Objects.  From what Ive read, this is causing the problem and creating the events in the log.  What is the best steps to get rid of this error message and clean things up.  Like I said before, our email server is running fine and there have been no problems, just this pesky error message in the event log.

Please advise.
