Problem accessing public folder

Hi,

I have issues with public folders:

When i try to access to public folders an error saying that the public folder is not found.

I have launched the Exchange BPA. It gives me an indication : "Site folder server deleted"

I applied the solution mentionned here :

Now the BPA do no more give this error. But I have same problem: I cant access public folder.

Any thing to check?

Thanks!
