convert OLM file to MBOX File

Mac Outlook data is saved in the OLM file which contains emails, calendars, tasks, notes, contacts, etc. OLM files are only accessible in Outlook for Mac OS. If you have to use OLM data in some other email clients such as Thunderbird, Apple Mail or any other MBOX-supported email application, then you have to convert OLM file to MBOX file format.

MBOX is the universal format that is supported by many email clients whether it is On Mac, Windows, or any other platform. You can easily import the MBOX file into any email client. I have seen many users of Mac Outlook posting on forums about how can they transfer their Mac Outlook data to MBOX-supported email clients. Following are the type of queries I found most interesting on those forums:
