I have 3 mailboxes with a large amount of messages in each mailbox.I do not want to delete mailbox because they are part of a ACD group but would like to know if I can delete messages and then change class of service to not allow message taking.Currently I can delete one at a time, but because of the number of voicemail's in each box it will take me up to 3 days to remove everyone of them..any ideas...
