I must have hit the wrong key using a message and all of a sudden Thunderbird has renamed my All Mail folder to Archives. I have spent a large number of hours trying to self-help, but alas, I am at my wits end. At this point in time I have two folders named Archives, one with all my messages and one that is empty. I even uninstalled and downloaded Thunderbird onto my Windows 11 desktop PC. Anyone care to help an old IT software developer? My objective it to somehow get back to having only one All Mail folder

Thanks, Brad
