I am missing some sub folders and also can not create new subfolders. A saved profile does have those subfolders in it but will not show in thunderbird. When I try to create subfolders the "Create Subfolder" is greened out. I have a very old profile from Windows 10 but Idon't what to use it as I would lose my latest emails which are important. What parts of the thunderbird program could be causing this and how do I get my subfolders to show in Thunderbird if they are in the profile.
