Question details

The user needs to resolve an issue where a shared Microsoft Bookings page is not sending confirmation emails or calendar invitations to staff and customers.

Product: Microsoft Bookings
Device & OS: not provided
Scenario: Managing customer appointments and staff schedules using a shared Microsoft Bookings page.
Observed behavior: Follow-up and cancellation emails are successfully delivered, but initial confirmation emails and calendar invitations fail to send. Staff receive silent calendar entries without any notifications or approval requests.

Before you start

Verify that all email notification settings are properly checked within your specific Bookings service configuration and ensure that recipients have checked their spam or junk folders.

Solution 1

Verify Email Notification Settings in Bookings

Ensure that confirmation emails are properly enabled for the specific service in Microsoft Bookings before escalating the issue.

Sometimes, the service-level settings in Microsoft Bookings might be misconfigured, preventing confirmation emails from being generated even if reminders work properly.

Open Bookings Services

Navigate to your Microsoft Bookings dashboard and select 'Services' from the left-hand navigation menu.

Edit the Affected Service

Click on the specific service that is failing to send out confirmations to open its configuration page.

Check Email Notifications

Scroll down to the 'Email notifications' section. Ensure the checkbox for 'Notify the business via email when a booking is created or changed' is selected, and verify that customer confirmation settings are active.

Solution 2Recommended

Submit a Microsoft 365 Support Service Request

If standard settings are correct, the issue likely involves backend Exchange routing or delivery logs. A Microsoft 365 administrator must escalate this to Microsoft Support.

Frequently Asked Questions

Why do Bookings staff receive calendar entries but no email notifications?

This can happen if the 'Notify staff via email when a booking assigned to them is created or changed' option is disabled in the Bookings Service settings, or if Exchange backend routing rules are silently dropping the notification payloads.

Can a non-admin user contact Microsoft Support for Bookings email failures?

No, because investigating failed email deliveries requires access to Exchange backend message-delivery logs. A designated Microsoft 365 administrator must log in to the admin center to submit the service request.

How can I check if the Bookings confirmation emails are being blocked by spam filters?

Ask your customers and staff to check their Junk or Spam folders. Additionally, your Microsoft 365 administrator can run a Message Trace in the Exchange admin center to determine if the emails left the server or were filtered out.
