I have set up a CCR tree that allows callers to leave a message on various mailboxes. It has functioned fine until recently it has begun to cause problems. When a caller tries to leave a message on any of the mailboxes they are given a message saying that there isn't enought room to leave a message. All of the mailboxes have been emptied and if a caller is routed to any of these mailboxes by the receptionist, they can leave messages just fine. Any suggestions on how to fix this? Thanks
