Problem with Outlook 2003 and public folders in Exchange 2000

[Roberto T.]

I have a Outlook client with a strange behaviour that started on friday.
Expanding public folders outlook hangs forever, other users could see the
public folder tree without problem.
I thought it was a problem with Outlook 2003 in that computer and I could
reinstall Outlook, but trying with the same user from a different computer
we found the same problem.

The problem has solved asking Outlook to check the size of the public
folders. Doing this, Outlook has found again the contents of the public
folder tree.

Does anybody know what has happened?

Thanks in advance,
Bob
