When I upgraded to the current Thunderbird last week, my main email folder (PurepianoInbox) that is not "Inbox" (where most of my e-mail comes) got converted to an archive folder, or so it seems. Specifically, the folder icon was replaced with the archive icon, and now this folder is located above my junk folder next to my archive folder. Ironically, it is still receiving mail correctly, but I want it to be returned to my list of mail folders because this is very confusing. (See the attached graphic). I have been trying to get an answer but so far no one has given a helpful response. Thanks!
