There are lots of options available for the conversion of OLM to PST on Windows but there is a penalty of solutions for the Mac OS. I recommend a software named OLM to PST Converter For Windows which is a Windows-based application and transfers the data from OLM file format to Outlook PST file format. To check how this tool works you can try its trial version. Visit:- https://www.osttopstapp.com/olm-to-pst.html
