How To Move Outlook Archived Folders To eM Client

I use eM Client as backup to Outlook, don’t trust Microsoft and their constant updating which creates constant chaos…

Outlook moved all my emails in a number of different folders into an Archive folder beyond a certain date - they just moved every email before March 2023 into this new Archive, I assume it is a local folder.

eM still has the identical emails that Outlook has, they are in sync, but without the local folders that were set up in this new Archive.they just went away.

How do I get those archived folders and emails into eM?

Thanks in advance…
