If you're using an older email app, generate an app password and use that for your account password. Then, use this info to configure your app To resolve this, move some of the email to a new folder in your account. Either edit that entry or add a new entry. There may be an entry in the resulting list that was created when you entered your account details. In the Account Settings dialog, in the left pane, select Outgoing Server (SMTP) from the bottom of the list.

Limitations for large folders - Folders containing upwards of 1 million or more emails will have issues downloading all the messages. Therefore, SMTP servers are created separately from email accounts.

Make sure your app is set to download the full contents of your email for offline use.

Backing up your email? Some apps default to only download a preview or snippet of your emails until an email is opened.

Click on your gmail account then under 'outgoing server' check what server is chosen by default then click 'edit smtp server. In order to check the outgoing server's credentials go to Mail menu > Preferences > Accounts > find your Gmail account.

Keep a copy of your email in your account - If your app asks you if you want to 'keep mail on the server' during setup, select 'yes,' or your email will be deleted from your account when it's downloaded. As stated before, all this means is your outgoing server credentials are incorrect in the Mail App.
