Dynamic Business Central 365: Set Up SMTP Mail in Business Central Using Gmail (Step-by-Step Guide)

Sending emails from Business Central is a common requirement, whether it is for posting sales invoices, sending reminders, or delivering notifications. Many users prefer Gmail as their SMTP provider, but a standard password will not work due to Google’s security restrictions. This blog explains the correct method to configure Gmail with Business Central using an App Password.

Introduction

If you try to set up Gmail in the SMTP Mail Setup page using your normal Gmail account password, Business Central will throw an authentication error. This happens because Google blocks sign-ins from applications that do not support modern authentication, unless you use a secure App Password.

In this blog, we will walk through each step required to configure Gmail successfully.

Why Regular Password Does Not Work

Gmail does not allow direct SMTP authentication using your standard password. To protect your account, Google mandates that you generate a unique App Password for external applications such as Business Central.

Therefore, even if your username and password are correct, Google will reject the connection until an App Password is provided.

Go to the Security section.

Before generating an App Password, you must enable 2-Step Verification.
Without this, the App Passwords option will not be visible.
