I guess I'm still planning to move to TBird.... someday.

If you ever do, then I advise to *first* clean up your (OE) folder
structure in such a way, that the tree of mail folders is structured the
exact same way as the corresponding (Windows) files.

Reason: The Thunderbird ImportExportTools Add-on is not aware of OE's
mail folder structure, as it is defined in (IIRC) the folders.dbx file.
So ImportExportTools uses the (Windows) *file* tree to decide what to
put where with which name, instead of the OE *mail folder* tree.

I.e. if you don't pre-clean/pre-check you might/will end up with a
totally messed up TB mail folder tree, both structure-wise and name-wise
(unless 'Singapore A c67' is an airline :-)).

There are quite a lot of other TB quirks for the OE/WM/WLM user to
overcome, but this is the most important one.
