[fetchmail]Retrieving Messages via IMAP from Exchange Public Folders

I can retrieve messages from my inbox, using the syntax: INBOX/folder

This is assuming Mailbox/INBOX/Folder, so how can I retrieve messages
from Exchange public folders, which live parallel to my mailbox?  Is
this possible?  

I couldn't find a list archive, so I'm hoping this hasn't been
discussed.

Any help greatly appreciated.

Also, if this helps at all:
[root(_at_)dhgcentral root]# fetchmail --version
This is fetchmail release 6.2.0+IMAP-GSS+NTLM+SSL+INET6+NLS

Thanks,
.jon
