How to Fix Booking Emails Going to Customers' Junk Folders
Question details
Users are experiencing issues where automated booking reminders and confirmation emails are unexpectedly routed to their customers' junk or spam folders.
- Product
- Microsoft 365 Bookings
- Device & OS
- not provided
- Scenario
- Sending automated booking confirmations and reminders to customers.
- Observed behavior
- Legitimate booking emails are being marked as spam and delivered to the junk folder instead of the recipient's primary inbox.
Verify with affected customers whether the issue is isolated to specific email providers (like Gmail or Yahoo) or if it is happening across all platforms.
Investigate Domain and Contact Microsoft Support
Determine the scope of the issue and request a backend investigation from Microsoft to clear any organizational domain block lists.
Check whether only Microsoft Bookings reminders and confirmations are affected, or if all outgoing mail from your organization is landing in junk folders.
Review your sender authentication settings and verify if your organizational domain has been flagged or placed on any third-party email block lists.
Have your Microsoft 365 administrator log into the Microsoft 365 admin center, navigate to Support, and submit a ticket requesting a backend investigation of the Bookings service.
Instruct Customers to Mark Emails as Not Junk
A temporary workaround to help train recipient email filters that your booking confirmations are legitimate.

Frequently Asked Questions
Why do only my booking emails go to junk while regular emails deliver normally?
Booking emails are often sent through automated backend services that might have different routing or sender reputation profiles compared to your standard outgoing user mail, causing strict spam filters to flag them.
How can I permanently prevent my business emails from being marked as spam?
Ensure your domain's SPF, DKIM, and DMARC records are correctly configured. This authenticates your identity to recipient email servers and significantly improves overall email deliverability.
Will having one customer mark an email as 'Not Junk' fix the issue for everyone?
No, marking an email as 'Not Junk' only trains that specific recipient's personal email filter. If your domain is on a wider block list, a Microsoft 365 administrator will need to resolve it at the backend level.
