Lee Ann,
A few suggestions that I found off the net:

Apply the latest Exchange Service Pack. From a newsgroup post: "When a public
folder is mail enabled, the Web Storage System needs to create an object in
Active Directory for that folder.  Usually this message indicates a
permissions error in Active Directory. Review the Event Viewer for messages
from the system attendant." 
Also from newsgroup posts: "If you try to pull up properties on the PF
objects in ESM, do you get this error: The mail proxy for this folder can not
be found. This may be due to replication delays. The mail enabled pages will
not be shown. ID no: C1038a21 If so, are you running Win2k SP2? There was a
fix for a problem that sounds a lot like this included in Win2k SP2.
Alternately, ensure that your computer account is a  member of the "Exchange
Domain Servers" group in the Users container. In order for the RUS to process
objects such as these PFs successfully, your computer account must be a
member of this group, and the permissions for this group must be applied
throughout the AD."

As per Q309793: "This behavior can occur if the display name of a public
folder is longer than 255 characters. The system attendant can neither create
a public folder proxy object nor truncate the name.". The article confirms
that this is an issue with Exchange 2000.

Q318552 specifies that "These errors can occur when there is a disjoint
namespace, where one or more child domains are not under the root domain in
the forest.". The latest Exchange service pack should solve the issue.

From Q278441: "This problem can occur if the public folder has not been
stamped with a proxy address (for example, pubfolder@". The Q
article provides the workaround.

 Tip #3  I don't know how the Remote Registry Service is tied into AD or E2k,
or how it was set to manual, but starting the service and
unmounting/remounting the public folders fixed a week long problem:
This problem can occur if the public folder has not been stamped with a proxy
address (for example, pubfolder@<domain>.com). Here are some possible
1. Stop and restart each of the Exchange 2000 services. Restart the server. >
Run Exchange 2000 Setup again with the /DomainPrep switch.
2. Apply Service Pack 2 for Exchange
3. Check to see that the Remote Registry Service is running on the Exchange
2000 server.
4. Rerun setup with /reinstall switch.  Reapply latest service pack.  
5. Reboot if prompted.

 If the System Attendant service is started with an account other than the
Local System account this can be the cause of event ID 9543. This event is
generated when the Recipient Update Service cannot stamp email addresses on
public/system folders. To resolve this issue, start the System Attendant
service using the Local System account and rebuild/update the Recipient
Update Service.

        Have an Exchange 2000 Server on a network w/ 2 W2K Domain Controllers
        less than 50 users. Both servers have SP3 and the Exchange server has
        No child domains. System Attendant is running under local system
        Users seem to have no problems, but the Application log is putting
        every couples minutes w/ Event ID 9543 w/ source MSExchangeIS. The
        description is similar to (see below):
        Have searched MS site and the results do not appear to apply to this
        situation... Right now there are no additional Public Folders in the
        Exchange Server. Any insight would be appreciated.
        Thanks much.
