Yes, they can. There is a 500 item limit for the inboxes I believe, after that, they go into limbo if anyone sends you anything before you clear your inbox out again. The worse part is no one gets a notice that this has occurred. There are other ways to lose CLs also but for me that one is the most annoying.
