Unbale to view some folders in Public Folder in Exchange 5.5

[tming]

I am using a exchange 5.5 server.
When i click some folder on the Public Folder.
It shows "Unbale to display the folder. This folder cannot be opened because there is a configuration problem on the server. Contact your Microsoft Exchange Server administrator for assistance."

Also, when i click on the property of same folder in the Microsoft Exchange Administrator. It shows "Microsoft Exchange Server Information Store ID no: 80004005-0507-00000000"

Can anyone help?
I am waiting.

I find the result that there is no replica on my site.
So, i cannot see the server content.
