Domain troubleshooting: Unable to connect to the Google email server in Email from your domain

If you receive a connection error when setting up Email from your domain with a Google email server, it may be a very simple issue to fix. ScheduleOnce uses a basic SMTP connection to connect to your Google Account. The connection is completely secure and ScheduleOnce does not have access to your Google login. However, Google considers basic SMTP authentication to be less secure than connecting through the Gmail API. Therefore, you must either enable access to less secure apps OR use 2-Step Verification with an application-specific password, depending on the authentication setting of the Google account you are trying to use for Email from your domain.

 

Enabling less secure apps

  1. Log in to the Google account of the mailbox that you wish to use for Email from your domain. The access to less secure apps setting is account-specific, so you must update the Google account for the mailbox you wish to use.

  2. Go to Google account -> My Accounts -> Security -> Less secure app access.

  3. Next to Allow less secure apps, select Turn on (Figure 1).

  4. To enable access to less secure apps in your Google Account:

    Note Access to the less secure apps setting will not be available and will be hidden, in the following scenarios:

 

2-Step Verification

If you are using 2-Step Verification, you will need to generate an application-specific password in the Google Account and use it as your password in the Send Email from your domain page. Learn more about G Suite passwords
