Hello, I have two email addresses, one personnel, one business. The other night, Thunderbird asked me to download an update. Since downloading the update, all my business emails and subfolders are gone and have been replaced by my personnel email address and subfolders. (in the left hand pane - pic attached) The business emails and subfolders are on my main server yahoo, but are not on my Thunderbird program. Can someone help me to recover the business email address emails and subfolders? Thank you.
