I recently added another account to my Thunderbird portable email. I then decided that I didn't really need the other email account, so I deleted it. Now, all of my email that I had stored on there is gone. Folders and all. When I go into my flash drive, I can still see the folders listed in there, but then don't show in Thunderbird. It seems to have created a new email folder. It now has a -1 at the end. How do I get all of my email back to the way it was?
