Migrating from Outlook.com to Microsoft 365 Business Basic

I am currently testing Microsoft 365 Business Basic.
My users mail boxes are all on Outlook.com. I need those mailboxes migrated to Microsoft 365 Business Basic.
This seems impossible as PST files are not supported by that subscription and IMAP is not supportes either.

What are the right way to migrate users mail boxes from Outlook.com to Microsoft 365 Business Basic?

  • You may not directly import Outlook.com mailboxes into Microsoft 365 Business Basic using PST or IMAP, but you can migrate them by connecting Outlook.com accounts to Outlook desktop and then moving mail into the new Microsoft 365 mailboxes, or by using Microsoft’s migration tools (Mail Migration Advisor, Exchange Online import service, or third‑party migration utilities).

      I did not find the option of moving mails from Outlook desktop (or any other mail client) to 365 mailbokses to be supported and work. Actually, it all seemed like a dead end. My solution was to discarding Microsoft 365 becuse af that, and ended up with a local web mail provider instead.
