How can I retrieve emails I deleted by selecting wrong parameters in the wrong area. I was in Thunderbird > Acct Settings > Synchronization & Storage and saw "Disk Space" settings. Without thinking I selected --> O ... Delete messages more than [ xxx ] [ ^v ] days old and I changed the number to... [ 90 ] days old. Like an idiot, I for some reason thought I was dealing with messages in "Trash"... go figure. So of course I then noticed in my email Accounts... all messages older than 90 days were removed from all of my folders I had set-up. Many of the folders are now blank, empty of emails that I had moved into the separate folders set-up for different information. I've explored tons of solution responses in "Support" but haven't found a solution to my problem. I really need my older emails back... please help! , Ron.
