Frequently Asked Questions

Common questions about Web357 Mail Connect for Microsoft Outlook 365

By default, WordPress sends emails via the PHP mail() function from your hosting server — which often ends up in the spam folder or gets dropped entirely. Sending through Microsoft 365 / Outlook means your emails go out from a real, authenticated mailbox over the official Microsoft Graph API, dramatically improving deliverability and meeting Microsoft's modern authentication requirements.

Yes. That's exactly why this plugin exists. Microsoft has deprecated basic authentication (username + password SMTP) for Exchange Online and Microsoft 365. Microsoft Outlook 365 Mail Connect uses OAuth 2.0 + the Microsoft Graph API, which is the official, supported way to send mail from third-party apps going forward.

No. The plugin uses Microsoft's modern OAuth 2.0 flow. You connect your Microsoft account once through a secure consent screen — no app passwords, no plain-text credentials stored anywhere on your site.

Yes. The plugin supports Microsoft 365 (formerly Office 365), Outlook.com personal accounts, and Exchange Online mailboxes registered in your Azure AD / Microsoft Entra ID tenant. Just connect the account you want to send from.

Yes. The plugin routes every wp_mail() call through Microsoft Graph, so every email triggered by WooCommerce (order confirmations, receipts, low-stock alerts), Contact Form 7, WPForms, Fluent Forms, Gravity Forms, MemberPress, LearnDash, and any other plugin is automatically delivered via your Microsoft 365 mailbox.

Yes. The plugin includes a built-in Test Email tool that sends a real test message right from the admin.

Click the "Delete Access Key" button in the Configuration tab to remove the plugin's credentials. You can also revoke access at any time from your Microsoft account / Azure portal under "Enterprise applications" → your app → Permissions.

Yes. The plugin stores only the OAuth access and refresh tokens needed to send mail on your behalf — no Microsoft account password is ever stored. All communication with Microsoft happens over HTTPS using the official Microsoft Graph API.

Yes. OAuth connection and sending via Microsoft Graph, plus the Test Email tool, are all free — there is no paid upgrade.
