Amazingly good. Works perfectly.

For once, software that actually does what it claims, without problems or complexity. I had some very, very old PST files, from the 1990s. It handled them as well as the newer ones. It creates individual EML files or MBOX files.

The only feature I wish is that when exporting EML files it would honor the folders and export EML files into filders, rather than everything into one giant folder with 20000 messages.
