Fix Website Contact Form Emails Missing from Exchange Message Trace
Question details
WordPress Contact Form 7 emails are not arriving in Microsoft 365 mailboxes and are completely missing from the Exchange message trace.
- Product
- Microsoft 365 Exchange
- Device & OS
- not provided
- Scenario
- A user is trying to receive website form submissions in their Microsoft 365 inbox, but the emails are not being delivered or logged in the system.
- Observed behavior
- Emails from the website are successfully received by other email systems but fail to reach Exchange Online and do not appear in the message trace logs.
Ensure you have administrative access to your Microsoft 365 admin center, domain DNS management console, and WordPress website dashboard before making changes.
Verify DNS Records and Test Default Routing
Checking your domain's DNS configurations ensures Microsoft 365 is properly set up to receive incoming emails from external servers.
If messages are not showing up in the Exchange message trace, they are likely being dropped before they even reach Exchange Online due to invalid or missing DNS configurations.
Log in to your domain registrar's DNS settings and ensure your MX records correctly point to your Microsoft 365 domain.
Confirm that your domain's SPF record includes the IP address of your website's server so Exchange doesn't reject the incoming messages as spam.
Change the contact form recipient to your default yourdomain.onmicrosoft.com email address to see if the issue is tied specifically to your custom domain routing.
Route Website Emails Through a Third-Party SMTP Service
Using a reputable SMTP provider bypasses strict Microsoft 365 spam filters that often block direct web-server emails.
Manage Your Business Documents Effectively with WPS Office
While managing Microsoft 365 server settings can be complex, handling your daily documents shouldn't be. WPS Office is a free, lightweight, and highly compatible alternative to Microsoft Office that lets you create, edit, and share Word, Excel, and PowerPoint files without expensive subscriptions.

- 3. Open and Edit: Launch WPS Office and instantly open your existing Microsoft Office documents.
Frequently Asked Questions
Why do emails reach Gmail but fail to reach Microsoft 365?
Microsoft 365 uses strict Edge Protection filters. If a web server sends emails directly without proper SPF/DKIM authentication, Microsoft 365 may drop the connection entirely before the email reaches your inbox or the message trace, whereas other providers might just send it to the spam folder.
What does it mean if an email is missing from the Exchange message trace?
If an email doesn't appear in the message trace, it means the Microsoft Exchange Online servers never received the message. The rejection happened at the DNS or network level before the email hit Microsoft's infrastructure.
How do I test if my WordPress contact form is actually sending emails?
You can temporarily change the recipient email address in your Contact Form 7 settings to a personal email (like Gmail or Yahoo) to verify if the web server is successfully generating and dispatching the message.
