Is there a way to empty all of the Trash directories How do you empty the Deleted Items folder of all mailboxes which have not been emptied? To manually empty all "Deleted Items" folders for all users' mailboxes, simply open the windows FIND "File & Folders" and search for: Deleted Items within the BOX directory From the results window highlight all the folders and DELETE This will remove the folder, however when someone deletes another message the folder will be automatically created unless you follow the instructions within KB Doc: 10147 to disable the option to save a copy of deleted messages.
