Recovering years of emails from Local folders
I have been using Thunderbird for years and each month I move emails that I wish to retain into a local folder for the year, and a sub-folder for the month. Around the New Year I opened TB and saw a message saying nnn mails being deleted from 2009 10 i.e. the sub-folder for October 2009. I had not initiated that delete and it seems that a background task has deleted all mails from the local folders. There is no evidence of them being in the local trash folder, or in the Windows recycle bin. If I change the view in TB to display the size of the folders it is showing a volume consistent with them being present, just invisible. How may i recover these mails? I have McAfee anti-virius installed and have run a full system search which has identified no events or virus present.

It sounds like your mail files are corrupted. First of all create a backup of your Thunderbird profile folder. https://support.mozilla.org/kb/profiles-tb#w_backing-up-a-profile
Then try to rebuild the index file of the troubled folder. Right-click the folder - Properties - Repair Folder
Note: depending on the corruption this may erase messages from the affected folder which cannot be recovered anymore. In that case you'd need to restore them from a recent backup done prior to the corruption.
Corruption is often caused by anti-virus software messing with Thunderbird mail files. It is therefore recommended to create an exception for the Thunderbird profile folder, so that the real-time scanner won't attempt to scan the profile with your mail.
