Moving Folders from WLM to Outlook

Hi folks
Hope you can help with a little problem I have with Windows Live Mail. In a recent update of Win 10 I found that WLM was no longer working and told by Microsoft that they had withdrawn support. I'm now using Outlook which is part of Office 2019.
I find myself with several folders containing WLM emails, many of which are very important to me. I can't use WLM to shift them to Outlook as it now refuses to do so.
Is there any way that the folders can be transferred manually to Outlook to anble Outlook to read them. Maybe it's a shot in the dark but I hope you might be able to point me in the right direction so that my email files/folders can be saved and also be made readable. Thanks for your help.
