Solved We couldn't access this account (Windows Mail & GMail)

I've had this problem before and got past it, but I can't remember how I did it now.
My Windows Mail app stopped working correctly, but just on this computer. Problem: No mail going out. Just sitting in Outbox.

Tried Repair, then resorted to Reset. Trouble. Added my account back into the app and into the People app, but I'm now repeatedly getting this in Mail whenever I try to check my mail (Note: just on this PC; my other PC's Mail app is working just fine):
"We couldn't access this account: ___________. You might need to update your password or give this account permission to sync to this device."

I've checked in GMail online, checked my password, turned off two-factor (temporarily), and checked my permissions list in GMail.

I've re-done the account three times: all names, addresses, IMAP and SMTP servers, all appropriate boxes checked. Restarted 4/5 times. Closed and opened Mail many times.

Can't think of anything else to do. If all else fails, I can go back to my latest MR image, but that will put me back to the broken Mail state, with no mail going out.

If you know the secret to beating this, please share it with me. Thanks.

Hi Wisewiz,
For one reason or another, you are not connecting with your mail-out server.
You need to check if you are using the correct settings, the outbox should not be set to IMAP.

smtp.gmail.com
Requires SSL: Yes
Requires TLS: Yes (if available)
Requires Authentication: Yes
Port for SSL: 465
Port for TLS/STARTTLS: 587

Check.

Incoming Mail Server: imap.gmail.com:993

Account Type: IMAP4

Outgoing SMTP email server: smtp.gmail.com:587

@OAT, @Edwin, @Porthos

Sorry to have bothered you all. I must have done something right, because it's started working again, and it's even SENDING now, albeit reluctantly (takes about 30-50 seconds to go).

Only thing I really changed after hearing from OAT was the IMAP and SMTP lines: I removed the :xxx from each of them. Maybe the app doesn't like being told which ports to use?!?!

Anyway, for now, it's working. Thank you all for looking at this (and thinking about it, ofc).

I don't know, but, I've never had much luck with Windows Apps!

Google/Gmail accounts are simple to setup in the Mail App, Windows 8/10/11 the mail servers are setup automatically. You just choose Google in the initial Account setup.
I've been using the Mail App for 8 years and one of the accounts is Gmail, thru those 3 versions of Windows.

There are variations in the speed of mail servers but that seems to be servers in specific areas or something. My Gmail servers are different from what others are saying. In some cases the server names do not show up in the Mail App.
