Hello everyone, I’m Kent, the website admin. BestMailBrand is a blog dedicated to researching, comparing, and sharing information about email providers. Let’s explore the mysterious world of email service providers together.

When it comes to setting up and managing email services, Office 365 (O365) offers a comprehensive solution for businesses. However, enabling SMTP basic authentication in O365 can be a bit tricky, especially if you're not familiar with the process. In this blog post, we'll outline the 13 steps you need to follow to enable O365 SMTP basic authentication, ensuring a smooth and secure email experience.

Step 1: Understand SMTP Basic Authentication

Before we dive into the steps, it's essential to understand what SMTP basic authentication is. SMTP (Simple Mail Transfer Protocol) is used to send emails, and basic authentication is a simple username and password-based authentication mechanism. Enabling this allows devices or applications to send emails through O365 using these credentials.

Step 2: Access Your O365 Admin Center

To begin, log in to your O365 admin center using your administrator credentials. This is where you'll manage your email settings and authentication methods.

Step 3: Navigate to the Exchange Admin Center

From the O365 admin center, find and click on the "Exchange" option. This will take you to the Exchange admin center, where you can manage your organization's email flow, mailboxes, and more.

Step 4: Locate the SMTP Authentication Settings

In the Exchange admin center, navigate to the "Mail flow" section and look for the "Connectors" option. Here, you'll find the settings related to SMTP authentication.

Step 5: Create a New Connector

Click on the "+" symbol to create a new connector. This connector will be configured to use SMTP basic authentication.

Step 6: Configure the Connector Settings

When creating the connector, you'll need to specify various settings, including the name, description, and the type of connector (in this case, an SMTP connector).

Step 7: Enable Basic Authentication

Within the connector's settings, look for the authentication section and select "Basic authentication." You'll be prompted to enter the username and password that will be used for authentication.

Step 8: Test the Configuration

After setting up basic authentication, it's crucial to test the configuration to ensure it works as intended. Send a test email through the newly configured connector to verify functionality.

Step 11: Update Your Applications

If you're enabling SMTP basic authentication for specific applications, ensure they are updated to use the new authentication method.

Step 12: Document the Process

Document the steps you followed to enable SMTP basic authentication. This will help future administrators or IT support staff understand and manage the configuration.

Step 13: Stay Up to Date

Keep up to date with any changes or updates from Microsoft regarding O365 and SMTP authentication. Microsoft may introduce new features or security measures that could affect your configuration.

By following these 13 steps, you can successfully enable O365 SMTP basic authentication, ensuring secure and reliable email communication for your business. Remember to regularly review and update your settings to maintain the highest level of security and performance.
