| User Message | An error has occurred when sending an email via the specified SMTP endpoint and credentials. An unknown error occurred sending an email via SMTP. (ExternalError) |
Scenario: Error or email is not delivered after configuring an SMTP connection with a Gmail account.
Problem: This error happens because we are now trying to connect to the Google account from a different location. Google sees this as suspicious about the connection and tries to challenge it, but we cannot respond.
** Please note that is one option to resolve this issue. Since this is a security restriction from Google, we cannot determine if there are other options to resolve this issue. **

Instructions
Solution: The key here is to use a Google Account App Password. An app-password is a 16-digit passcode that gives a less secure app or device permission to access your Google Account. This is generated by Google.
Please use the following steps to generate an App Password (taken from a Google Account Help page)
Create & use app passwords
Important: To create an app password, you need 2-Step Verification on your Google Account.
If you use 2-Step-Verification and get a "password incorrect" error when you sign in, you can try to use an app password.

Add SMTP credentials
Now you should be able to use the SMTP Delivery Method to send an output document by using an email service.
