When configuring SMTP in Office 365, there are several best practices to follow:

• Secure Connections: Always use secure connections (TLS/SSL) when setting up SMTP. This ensures that email data remains encrypted during transmission, protecting sensitive information from prying eyes.
• Authentication Methods: Utilize modern authentication methods like OAuth 2.0 for secure and seamless access. This not only enhances security but also improves the user experience.
• Relay Settings: Properly configure SMTP relay settings to allow emails to be sent from your organization's domain. This ensures that emails sent via Office 365 are properly authenticated and not marked as spam.
