When Exchange 2007 was implemented, in the Org Config, Mailbox, Address Lists, there was an entry for PUBLIC FOLDERS. That entry was inadvertently deleted. We were not using it at all, but now all the Outlook 2007 clients who click it in the address book get the error
"Bookmark is undefined"
I have already tried to add a new address list called public folders, but that does not work. I am guessing that since it was a default list created when Exchange was installed that I must have to have special code in the recipient container.
