I lost my second search window for Thunderbird Mail so went to VIEW, TOOLBARS and selected all three options - MAIL, STATUS and QUICK FILTER. I got my search window back that enables me to search my emails for messages from a specific person. However, I then lost all of my folders (mailboxes) in my inbox - everything from A to Z bar two folders titled ALFIE and APPLE MAC EMAILS. These folders contain everything email like from my clients that is relevant to my business. Each folder is a client name and each contains any number of emails and replies. I clicked the REPAIR FOLDER option in order to try and do exactly that, repair the folders but so far that only appears to have been applied to the emails in my inbox, the ones that have not yet been filed in the individual folders. I moved to Thunderbird because I was told it was a safe and easy to use system but I am struggling with this aspect of it. Any help gratefully received!
