Hello! A very important email folder in my Thunderbird just vanished. I didn't touch anything! My email was downloading very slowly and so I closed the entire Thunderbird application. When I re-opened it, the folder was gone. Everything else is there as before - all other folders, my inbox etc. I have no idea what happened or where the folder went. I can't find anything online that addresses the problem or how to solve it. I'm very much a tech novice. I need a solution that a 5 year old could navigate lol This is happening on my laptop, Windows operating system. I don't have any email managers on my phone. S.O.S. Cara
