| | Personal Folders
Do you mean "yellow" public folders in your Lotus Notes mail file or "grey" private/personal folders that appear at the bottom of your folder hierarchy.
Because the folder is Private (only your user id can see it), the BES process "spying" on your mailbox can't get in to see what is there.
Recreate the folder as public and you should be all set.
