Someone scheduled a bookings appointment but it is not showing up on the calendar as reserved

Someone scheduled a bookings appointment but it is not showing up on the calendar as reserved. We did not know she was attending as we never received a notification and it didn't show up on the calendar. She has a receipt and received an appointment reminder. I don't know how to troubleshoot this.

Hi @Audrey Trieschman,

Thank you for posting your question in the Microsoft Q&A forum. 

I understand how concerning this can be especially when the customer received confirmation and reminders, but the appointment did not appear on your calendar or trigger any notification. I’ll be glad to help you look into this.

To better narrow down the possible cause, could you please help confirm the following details?

Which calendar are you checking (Bookings mailbox calendar vs. personal Outlook calendar)?
Is the issue affecting all appointments or only this specific booking?
Could the notification have been routed to Junk, Quarantine, or filtered by an inbox rule?
Has this scenario happened before, or is this the first occurrence?
When the booking was made, did anyone else on the team receive the appointment or notification?
For that staff member, is calendar sync enabled (e.g., “Events on personal calendar affect availability” or similar setting)?
If possible could you provide me a screenshot of the setting for the booking page ?
Could you try creating a test booking to check whether the issue persists?

Thank you again for your time and understanding. While my initial response may not resolve the issue immediately, I’d like to gather more details about your situation so I can assist you more effectively.     

I really appreciate your patience, and I’m here to help. Looking forward to your response!

Which calendar are you checking (Bookings mailbox calendar vs. personal Outlook calendar)? BOOKINGS

Is the issue affecting all appointments or only this specific booking? HOW WOULD I KNOW???

Could the notification have been routed to Junk, Quarantine, or filtered by an inbox rule? NO. THE APPOINTMENT ISN"T EVEN SHOWING UP ON THE BOOKINGS CALENDAR.

Has this scenario happened before, or is this the first occurrence? AGAIN, HOW WOULD I KNOW?

When the booking was made, did anyone else on the team receive the appointment or notification? NO

For that staff member, is calendar sync enabled (e.g., “Events on personal calendar affect availability” or similar setting)? YES

If possible could you provide me a screenshot of the setting for the booking page ?

Could you try creating a test booking to check whether the issue persists? WE HAVE SEVERAL BOOKINGS APPOINTMENTS SET UP. THIS ONE WAS FOR EVERY 30 MINUTES FROM 11AM TO 3PM. THERE WAS AN 11AM APPOINTMENT SCHEDULED, A 11:30 APPOINTMENT SCHEDULED, AND A 1PM APPOINTMENT SCHEDULED. THIS ONE DID NOT SHOW UP ON THE "CONFIRMED" SCHEDULED APPOINTMENTS, NO ONE RECEIVED A NOTIFICATION EXCEPT THE CUSTOMER.

Hi @Audrey Trieschman,

Thank you for your response, I really appreciate the information that you have given me.

To resolve this issue, Microsoft’s support team will need to be engaged. A technical support engineer can conduct a remote session to investigate the situation, verify backend configurations, and run any required synchronization tools. Since this case will likely involve collecting and analyzing logs, it is recommended to raise a support ticket to ensure a smoother and more efficient resolution process.

The Global Admin should create a service request with Microsoft support to get advanced technical assistance and diagnostics. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin.   

If you’re unsure who the Global Admin is within your organization, you can find guidance on locating them here: How do I find my Microsoft 365 admin? - Microsoft Support.  

As community moderators, I don’t have access to internal service logs, backend diagnostics, or engineering dashboards due to privacy and security restrictions. Issues that may involve backend or service related problems can only be fully investigated and resolved by Microsoft’s product engineering teams.

Thank you again for your time and understanding.
