I am still trying to recover lost emails from my inbox. I contacted Avast as it was suggested the anti virus program might be responsible but they insist it has nothing to do with them. I can not find a contact telephone number for Thunderbird support in Australia so am trying this forum again in the hope someone can tell me if I can recover these lost emails. I tried instructions from one website but after finding the Local folder in Account settings the options described in the instructions did not match what was available to me so I was not able to go any further. I am considering trying 'Easeus' which is a free download that claims to fix this kind of problem and gets quite good reviews, I am just concerned that I'll hit a brick wall again if the tabs or options in a particular file don't match the instructions as that leaves me nowhere to go. I even allowed a local computure guru remote access to my laptop but he couldn't work out where the missing emails were which is very concerning as I had hoped he had seen this kind of problem before as there are so many articles on line about missing emails with Thunderbird. I hope someone can offer some suggestions. Cheers Alex
