I have used MailStore Home to archive then export an Outlook PST file into Thunderbird. The Export appears to have worked, but I notice that the resulting file structure in Thunderbird Local Folders has "MailStore Export / Outlook Outlook Data File / Inbox", with all my folders residing under the inbox folder (which they should). Is there a way I can change the Local Folder structure to remove the top level "MailStore Export / Outlook Outlook Data File" and leave the top level as "Inbox"? See image.
