On Dec 3 2024 imap.comcast.net deleted my Inbox and all it's subfolders for some unknown reason. It was never fully recovered, but most of the sub folders were recovered and exist at imap.comcast.net with the original content. Thunderbird does not show these sub folders under it's Inbox, any idea why? Anyway, since then, thunderbird Inbox will not allow me to create a folder that has a name listed in the imap.comcast.net list of sub folders. any idea why that is. Thank you for any help you may offer. Peter
