When you mail enable an Exchange 2000 public folder, you may encounter duplicate public folder proxy objects in the directory for these public folders. A public folder proxy object is an entry in the directory that contains all of the mail-related attributes for the public folder (for example, e-mail addresses). If duplicate public folder proxy objects exist for a particular public folder, mail that is addressed to that public folder may not be delivered.

Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server.
After you upgrade an Exchange Server 5.5 computer to Exchange 2000, and then switch the organization to native mode, any attempt to mail enable a public folder (that was created in Exchange Server 5.5 before the upgrade) causes the creation of a duplicate public folder proxy object in the directory. Any public folder that you created on the Exchange Server 5.5 computer before the upgrade gives you the Mail Enable option. If you click Mail Enable to mail enable the folder, a second object is created in the Exchange System Objects container (in Active Directory).
