Moving/Copying Folder from Mailbox to Public Folder fails.

I have a user running Office 2K Pro SP2, using Outlook to get e-mail over an Exchange 2K server.  She tried copying a folder from her mailbox to Public Folders, and gets an error:  "Can't copy the items.  Can't copy folder.  A top-level folder can't be copied to one of it's subfolders.  Or, you may not have permissions for the folder.  To check your permissions for the folder, right-click the folder, and then click Properties on the shortcut menu."

I checked the permissions on the destination side and this user has the Owner role assigned to her.  I also added her on the security end in System Manager, but no luck.  I then exported the folder she wants to a PST, and attempted and import to Public Folders with no success (I didn't get an error nor did anything happen).  I then tried to import the PST into my mailbox, with success.  I tried to move and copy the folder without success.  I've checked, rechecked, and checked again, everything on the Exchange Server, the Public Folders, and the Folder I'm trying to move/copy, and everything looks fine.

I can create a folder as the user in her mailbox, then move/copy into Public Folders without fail, so I don't know what the problem is.

Your assistance is greatly appreciated.

Cheers,

David
