I use Norton Internet Security for Internet and Email anti-virus. Recently the software popped a prompt saying there was an issue with the SENT folder in my Mozilla Thunderbird 31.4.0 and the recommended action was "Delete". I did use that option and started using my emails but only today I learnt that all emails prior to my opting for the DELETE option do not have the content anymore (the email exists with the header but with no body). How do I get those emails back? Please suggest asap .. thanking you
