I have been using a email client since 1999, Outlook express at first and later thunderbird for almost 20 years. I have a hotmail (pop) account and a Gmail ( pop) account. Last friday, thunderbird got blocked and could not complete to download 6 messages. I had to stop de program. Those messages were visible on the webmail but Thunderbird never succeded to download them. I have had to forward them to myself to have them to get into my inbox. I removed a program called RAV endpoint protection that got in my computer recently and i tought it could be the cause. Later I noticed that all my all email i had since 1999 had disappeard. I have removed and reinstalled thunderbird yesterday. Now I can only see the email arrived since the new installation. Il have other accounts, imap and older email are still visible. Where a all those hundred of mails now? How can find them back? Many of them are still on the webmail but i have deleted many old one because i tought they were keept safely in thunderbird.
