Can't get Outlook desktop & Google paid account connect

I got a new computer, upgrading from Win10 to Win11.

Outlook 365 (16?) running on both computers. I have a Google domain account. PST file on old computer looked like it was saved in a Dropbox directory, which I know was not a good thing. So I created a new folder in users\[my name] and called it Outlook. I pasted the .pst file from the old computer there.

Went into new Outlook, File\Account settings\Account settings, and told it to add a new data file. I used the pst file in the new location.

 Then I told it to use that same file for email.

Oh, BTW, using control panel, went to mail and made certain the outlook data file was the same ... just in case. I configured everything there according to the GMail instructions. NOTHING was changed in Outlooks GMail settings. To the best of my knowledge, the only thing I needed was the super secret 16 character code for the password. (I first tried it with my "normal" password.)

Within control panel, when testing email settings, no bueno.

My old items are all there as they were before.

I did run scan.pst and it did say it found some errors which I told it to fix.

When a so-called expert tried to fix it, outlook downloaded EVERY EMAIL SITTING IN MY GMAIL "ALL MAIL"FOLDER. I went from 282 unread messages in my Outlook inbox to over 9,000. Oh, but although it said the messages were downloaded, NONE WERE ACTUALLY IN MY INBOX.
