Thanks for getting back again.
One option is to export project folders to PST files in New Outlook. PST archives can later be re-opened in Outlook, even years later. Alternatively, you can use export to .eml files option in new Outlook (Right click on any email-> Save as -> Save as eml/msg).
But kindly remember, no software can realistically guarantee 10 years of unchanged support, you will need to adapt your process over time.
