Using Thunderbird for over a decade on different computers. Like it very much. (sorry, english is not my native language) The mail account is on an imapserver. When I create in (provider)webmail a new submap under the inbox it doesn't appear on the desktop client. When I create a submap in Thunderbird all works fine, Even in webmail, mail shifted into the submap created in tb is visible in tb. Thanks in advance, bjorri.
