Outlook 365 - import/attach PST file that used POP3

Outlook 2013 64 bit

Outlook.com (as MS Exchange)
For several years, we were using desktop Outlook (2010, 2013) with our respective outlook.com emails, and also a couple of historic POP3-connected emails from our ISP, which had the ISP's email address (after the @). Example, Fred_NurK@iinet.net.au.

This was always a bit of a process if a computer crashed or was changed, to transfer the PST files and re-establish the connections. I haven't done it for years.

With the outlook.com accounts, there is never a problem, of course. While it is time and bandwidth -intensive, most of the "stuff" can be fetched from "the cloud", rather than hassling with the .OST file(s) on local disk. And all the attachments and Contacts etc come with the download.

So we decided on a (family, not business) Office 365 pay-by-year, which handles the outlook.com emails but left the POP3 accounts and their PST files (several, all GB-sized) stranded.
We do need to have access to the historic emails (many many '000s) and the various attachments and other Outlook components (Contact lists, etc).

As I see it, I need to attach the appropriate PSTs - but I am not sure how to do that with Outlook 365 (and I recall, with desktop Outlook, having to be careful not to create the email account and have an empty PST, and then have to somehow attach the very large older ones that I had saved). And I can't remember accurately where the PST files should be placed (? AppData something).

I will be very grateful if some kind person can direct me to a clear and simple procedure for this. I need to do it on a couple of computers.

Thx, Ian
