I vaguely recall doing this (or maybe it was giving up on it) 15 years ago, but don't recall how I did it. Maybe I exported the file and then read it in again. I use Office on my machine, but not the cloud version.

Two files, but yes.

But I want to migrate to Mac Mail, not gmail.

I bought PST Converter Pro Apped, $29. It converted the .pst files to .mbox files in seconds. Those then imported right into Mail.

I haven't bothered checking into the pop3 setup in Mail yet, but I probably will.
