If you're using a Google hosted email account (Gmail or Gsuite) then you'll need to do one of these 2 things for the account in use before the machine can send email. Either is done in the account settings for the account.
If 2 factor authentication is not enabled for the account. Enable the less secure apps setting.
If 2 factor authentication is enabled for the account. Create an app specific password and use that password when configuring the machine rather then the regular account password.
Alternatively you can skip all of the setup and download the "Scan to Cloud Email" app from the AppGallery and use that instead of the built-in email function. Doing that requires no setup on your part beyond installing the app.
