Rated 2 out of 5 stars

Many thanks to Kryclm for pointing to this new "ImportExportTools" at: http://www.nic-nac-project.de/~kaosmos/mboximport-en.html
and for doing it HERE. Ever since upgrading to TB 3.x I sorely missed SmartSave. I haven´t tested all functions of the "ImportExportTools", but exporting every mail of a folder to .eml (with attachement) or .html files (sadly without attachement so far) seems to work well.
Still two stars for SmartSave, because it worked so well with TB 2.x. :-)
