SYMPTOMS
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.

Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Microsoft Exchange 2000 Server service pack that contains this hotfix.

The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English version of this fix should have the following file attributes or later:

Component: System attendant



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server.



MORE INFORMATION
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).
