From the developer:
MacSonik OLM Viewer Pro for Mac is a top-notch utility that facilitates a user to first view, scan, and then convert the scanned items into several file formats. You can convert the scanned OLM files into MBOX, PST, EML, EMLX, and 8+ different file formats. Additionally, you can also split the resulting PST files into smaller parts to protect them from being corrupted.
