If your EScan is failing to send and you are using Gmail, there is a security setting called "allow less secure apps" that needs to be turned on. Follow these steps to turn this setting on.
If your office uses a GSuite Domain, you will need to have the administrator log-in to change these settings.
1. Log in to Gmail, click on the Account options (the 3x3 grid) in the top right corner and select "Account".
2. Click the "Security" option on the left.
3. Locate the "Less secure app access" setting. Click on the "Turn on access..." text.
4. If this option isn't available you will need to turn off 2-Step Verification.
Send a test Escan from your MyoVision software to check whether the issue has been resolved.
