ModernSMTP M365 – Secure Microsoft 365 Email for PrestaShop

ModernSMTP - Microsoft 365 SMTP with OAuth2 for PrestaShop

Send your store's emails securely and reliably using your Microsoft 365 account — no app passwords, no hassle.



ModernSMTP is a PrestaShop module that integrates your shop with Microsoft 365 (Outlook, Exchange Online) using OAuth2 authentication, the most secure and modern method to send transactional and marketing emails.

✅ Key Features:

• Secure SMTP with OAuth2 — Say goodbye to insecure app passwords.
• Microsoft 365 Native Integration — Authenticate via Microsoft Graph API.
• “Send As” Override Option — Choose a different sender address (with permission).
• Test Email Tool — Instantly verify configuration before going live.
• Multi-store Ready — Install on all your PrestaShop stores.
• No Monthly Fees — One-time payment, unlimited installs.

🔒 Why OAuth2?

Traditional SMTP with basic auth is being deprecated by Microsoft. OAuth2 ensures compatibility with current Microsoft 365 security standards, keeps your credentials safe, and improves deliverability.

⚙️ How It Works:

1. Install the module.
2. Fill in your Microsoft 365 App credentials (Tenant ID, Client ID, Secret).
3. Click "Authorize" and log in with your Microsoft account.
4. You're ready to send emails!

📩 Instant Delivery:

Right after purchase, you’ll receive the module as a downloadable .zip file via email — along with a clear installation and configuration guide. Everything you need to upload and start using it in your PrestaShop store, instantly.
