Troubleshooting Connecting Sugar to Gmail


    Sugar® instances may fail to connect to a Gmail account due to Google attempting to prevent suspicious activity. This issue can be encountered when any user is configuring a personal inbound email from their Emails module or when an admin is configuring a Group or Bounce-Handling account via Admin > Inbound Email. The resolution steps are the same for both and will be discussed in this article.

    Note: This article pertains to Sugar versions 7.9.x and earlier.


    When configuring an inbound email account to connect to Gmail, you may be unable to select a trash folder or be presented with an error message when attempting test the settings. This is an indication that Google is restricting Sugar from making the connection.

    To resolve this issue, you should first confirm your email configuration. If the issue continues to persist after the email settings are confirmed, you will need to remove any Google restrictions. The following sections provide detailed instructions on how to perform these actions. 

    Confirming Email Configuration

    Use the following steps to confirm that your Gmail settings are configured correctly in Sugar:

    1. Open the inbound email settings you are attempting to configure (i.e.(Admin > Inbound Email or the Emails module).
      Note: For more information on configuring system-wide inbound email accounts, please refer to the Email documentation in the Administration Guide. For more information on configuring your personal inbound email account, please refer to the Emails documentation in the Application Guide.
    2. Click “Prefill Gmail™ Defaults” to ensure that the mail server address, protocol, and port are correct.
    3. Re-enter the values for the User Name and Password fields.
    4. Click the Select button to the right of the Trash Folder field.

    If the Trash folder can be selected, the connection to Gmail was successful and you can choose the appropriate folder then click “Done” to preserve your changes. If you cannot access your Trash folder and continue to experience the issue described in the Symptoms section, please proceed to the next section.
