OLM file is not compatible with Mac Mail. So that makes importing OLM file into Apple Mail impossible. OLM is a proprietary format by Microsoft that is used solely by Mac Outlook to archive data. It is not read by any program or email client.
But there is a way to do this correctly.
And we are not talking about any of the techniques mentioned below.
Techniques Proven to Hurt You and Your data
We are not talking about simply forwarding the emails to an email account added in Apple Mail. That is plain inefficient and unrealistic.
Nor are we talking about using an IMAP sync method that can destroy your productivity (because it is that long and tedious).
And lastly, we are also not talking about dragging the folders from Mac Outlook to Mac desktop to turn them into generic MBOX files. Yes, this method works and many choose to migrate data this way. However, if you have a couple more than few folders, you are going to regret going this way.
Drag-and-drop technique can take you where you want, if you have one or two email folders. But anymore bigger than that, it is a road sprinkled with myriads of problems.
We are talking about using a professional, easy to use, and efficient third party solutions that convert OLM files into MBOX files.
But many of these tools can be even worse than the above mentioned manual techniques. However, if you are a busy person and cannot give away your time to research and find the best OLM to MBOX converter, do not worry. You couldn’t be at the better place, because we have already done it for you.

And unlike other typical file converters, it has a graphical interface with cleanly organized features, a sharp conversion algorithm to keep the data safe and secure, and a plenty of other functions to allow for flexibility and control.
After you have installed the tool, click on ‘Load OLM files’, and choose the OLM files you save above. Next, simply mark the folders you want to convert. The following step will ask you about additional settings or options that you can set according to what you want.
