I have 20 email inboxes that I monitor. I have not been able to get the dredge to work at all. I have tried /mailboxname/Messages, the mailbox name alone and several other combinations but I just can't get it to work.
Can you let me know how to get the dredge to work in my environment?
'/mailboxname/Messages' is correct and works fine here. Check if the 'Messages' folder is not empty (some are) and that you are using very last version.
