OLM Convert
The free, open-source OLM convertor.
A utility to convert an Outlook for Mac archive (.olm file), that can only be opened with Outlook for Mac, to a set of standard .eml files that can be opened by almost all email clients.
Output EML messages are organised hierarchically, for example a message contained in an OLM file will be output to an EML file like `"<output directory>/example@example.com/Inbox/Subject - Mon, 04 July 2022 21.04.56.eml"`.
Available as a GUI, a python command-line interface, and as a module.
Supports attachments but can only output emails with the HTML and plain text content types.
