Norton 360 reported that I had viruses so I allowed Norton to remove any threats but it deleted my entire Inbox and Thrash in Thunderbird. I've found that it moved those files to Quarantine and I've managed to recover my Thrash, but when I try to recover Inbox I'm getting an error "Failure-1000" saying that element cannot be recovered from Quarantine. In Thunderbird I can see all my messages in the Inbox but they are all blank/empty. Is there a way to fully recover them?
