The Unified folders option in Thunderbird is really only useful if you are using T'bird to manage more than one email account.
It provides an option to allow you to see the emails from all your addresses in one Inbox, Sent folder, Deleted folder etc as well under each individual email account.
To turn it on click on View in the menu across the top of the screen, then on Folders, then Unified
I have quite a number of email accounts and in T'bird I manage all of them from the Unified Folders section.

Will be interesting to hear if VM can recover those missing emails for you.
