How to Export Mac Outlook 2011 to Outlook PST?

Summary: Outlook for Mac does not export PST file. Instead, it exports mailbox items in OLM file format, which is not supported by Outlook for Windows or Office 365. Hence, to export data from Mac Outlook 2011 to PST, you need an OLM to PST converter software  or follow the workaround discussed in this post.
