Fix Microsoft Bookings Confirmation Emails Not Sending

Product: Microsoft Bookings
Device & OS: not provided
Scenario: Creating and managing appointments where automated email notifications are expected to be delivered to customers or staff.
Observed behavior: Participants successfully receive cancellation emails, but confirmation and reminder emails for new bookings are never received.

Before you start

Before troubleshooting, ensure you have Bookings calendar administrator privileges and verify that recipient email accounts are not routing automated Microsoft 365 messages to the spam or junk folder.

Solution 1Recommended

Verify Service and Notification Settings

Check the Bookings service settings to ensure that automated confirmation and reminder emails are properly enabled.

Incorrect service configurations often cause confirmation emails to be suppressed. Verifying these settings is the critical first step in troubleshooting the issue.

Access Microsoft Bookings

Open Services Settings

Navigate to the 'Services' tab from the left-hand navigation pane and click on the specific service you are trying to book.

Check Email Notifications

Scroll down to the 'Email notifications' section and ensure the checkboxes for 'Notify the business via email when a booking is created or changed' and 'Send a meeting invite to the customer' are selected.

Review Reminders

Check the 'Reminders and Confirmations' section to confirm that reminder emails are correctly configured, saved, and scheduled for the proper time intervals.

Verify Service and Notification Settings

Test Your Configuration: After saving any changes, create a test booking using a secondary personal email address to verify if the confirmation email is successfully delivered.

Solution 2

Escalate to the Microsoft Bookings Community Hub

If settings are correct but confirmation emails still fail while cancellations work, the issue may require backend investigation.

Frequently Asked Questions

Why do Microsoft Bookings cancellation emails work but not confirmations?

This specific behavior typically points to a backend service sync issue or a corrupted specific service configuration rather than a general mail-flow problem. Deleting and recreating the specific service within Bookings can sometimes refresh the backend and resolve the issue.

Can automated Microsoft Bookings emails be blocked by spam filters?

Yes, automated emails sent by Microsoft Bookings can occasionally be flagged as spam or junk by external email providers (like Gmail or Yahoo). Always ask clients to check their junk folders and whitelist your domain.

How do I customize the confirmation emails in Microsoft Bookings?

You can customize the email notifications by navigating to your Bookings calendar, selecting the 'Services' menu, choosing your specific service, and editing the text inside the 'Additional information for email confirmation' field before saving.
