Outlook 2019 not working with Gmail

I agree with ColleenLOBrien,

STEP 1: Set up 2-step verification ( I used a mobile phone and had them send me a text message with the verification code)
STEP 2: Then get the App Password from Google under "Sign in with Google"

STEP 3: Repair the particular account in Outlook 2019 ( File> Account Settings > Account Settings; Select the account and then hit Repair)
STEP 4: Enter App password. If it chokes; reverse steps 3 and 4.

IT SIMPLY WILL NOT WORK WITHOUT THE REPAIR STEP!!!
And, yes, each account needs its own app password.

I struggled all day with this and did not do any actual work. Having modified my server settings on the web-version of Gmail, I suddenly got hit with 512 e-mails from history when the access started working. That was my mistake. This whole mess, however, is Google's mistake for lying to decent people about Outlook 2019 being fine after 30 May. It clearly is not and they have caused me misery that I will not forget easily. I specifically bought my wife Outlook 2019 to AVOID THIS, fer cryin' out loud!!!

My mobile phone running Gmail as an app was OK with all three my Google accounts, but my tablet and desktop, running a Samsung e-mail client and Outlook 2019 respectively, both refused to work on two of the Google accounts. Both those accounts , however, worked just fine on the Gmail app on the mobile phone (!!?). The third Google account was just fine on all three machines. It turns out that the particular account ( that third one) ALREADY had two-step verification and app passwords.

We wuz lied to, and we iz upset. I Lost a lot of earning hours today through this 100% avoidable problem.

Who knows? Will we wake up to the same issue tomorrow?

Copying from a previous post - I did this and it worked. I had to add 2 step verification. To add the app password to Outlook - go via Repair and then Repair manually. Following was from a fellow warrior with this issue:

Create & use App Passwords

If you use 2-Step-Verification and get a "password incorrect" error when you sign in, you can try to use an App Password.

1. Go to your Google Account.
2. Select Security.
3. Under "Signing in to Google," select App Passwords. You may need to sign in. If you don’t have this option, it might be because:
   1. 2-Step Verification is not set up for your account.
   2. 2-Step Verification is only set up for security keys.
   3. Your account is through work, school, or other organization.
   4. You turned on Advanced Protection.
4. At the bottom, choose Select app and choose the app you using  Select device and choose the device you’re using  Generate.
5. Follow the instructions to enter the App Password. The App Password is the 16-character code in the yellow bar on your device.
6. Tap Done.

Tip: Most of the time, you’ll only have to enter an App Password once per app or device, so don’t worry about memorizing it.

ABHawk, I actually just started working again. I have a strange suspicion that it might have to do with their "less secure apps" changes but the fact that it started working again makes me wonder. Do you think Google is getting beat up by this and backed down from the changes? I use POP3 for a specific reason and prefer it over IMAP.

I have the same issue. I upgraded my Office 2013 to Office 365, recommended by Google Site. My IMAP connection to Gmail works, but POP does not.
