Here's the problem: My boss was having trouble with Outlook so we temporarily switched to Thunderbird until the problem was fixed. Now that it's fixed, my co-worker decided to delete both my Boss' account AND the program. My boss REALLY needs those emails he sent through Thunderbird back because of a job "you never said that/I never got that email" dispute, but they're not on the email server (Verizon). I read that his computer may possibly have those files still stored on the computer even after my co-worker uninstalled the program but I do know where to find them. Thank you so much in advance. PS - one more question: why doesn't Thunderbird sync ALL folders with the Verizon server so this doesn't happen and there's a copy of all emails sent through Thunderbird on the server?
