Customers are not able to reschedule meeting after booking

Dear @Wesoftek Connect,

Good day! Welcome to Q&A forum! 

To understand the situation better and provide you with the most suitable support, could you confirm the following information: 

• How long has this issue been going on? Are all of your customers affected or just some specific ones? 
• Are customers required to sign in before booking? 
• Is the booking page integrated with a Microsoft 365 business account or a personal account? 
• Have you enabled customer management of Bookings in the Bookings app, but it still shows the error code? 

Your confirmation would be very helpful! 

In the meantime, kindly try the following suggestions to check what might have caused the issue: 

• Clear cache & try booking on another browser: Ask the customers to clear their browser cache or try a different browser/device 
• Verify rescheduling settings: Please refer to this article for step-by-step instructions: How to let customers manage their booking | Microsoft Learn 
  • Go to Bookings > Booking Page 
    • Ensure the page is published and accessible 
      • Confirm that “Allow customers to book appointments” is enabled 
      • Reproduce the issue: Please try booking the same service yourself using different browsers and devices to see if the error code still appears 
• Review service setup: Check if the service has:  
• Valid staff assigned 
• Available time slots 
  • No conflicting rules (e.g., buffer times, max attendees) 
• Create a test booking and ask some other people to try to reschedule to see if the error persists

Please let me know when there are updates or if you need further assistance. Any updates you can share would be very helpful. I appreciate your time and look forward to hearing how things are going.

Here are the details you requested:

The issue is affecting all customers when they try to reschedule their bookings.

The booking page is open to everyone; no sign-in is required before booking.

We are using a Microsoft 365 Business account for our Microsoft Bookings setup.

The "Allow customers to manage bookings" option has already been enabled.

We have tried all the suggested troubleshooting steps, including clearing cache, using different browsers/devices, creating test bookings, and checking staff assignments, time slots, and service settings. The issue still persists.

Despite trying all these steps, the rescheduling error continues for all customers. Could you please escalate this to the technical team or provide further guidance on resolving this issue?

Dear @Wesoftek Connect,

Thank you for updating me with your detailed information and for your effort and time in doing the standard troubleshooting steps!

I sincerely apologize for the inconvenience caused by this issue.

I have tested on my end with a Test booking page open to everyone and "Allow customers to manage bookings" is enabled, I could reschedule the booking using another account with a different domain.

Based on your description, when the issue is affecting all customers when they try to reschedule their bookings, it's likely that there might be an issue with backend that requires further investigation.

To resolve this, Microsoft’s support team will need to step in. A Technical Support Engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.    

As forum moderators, we don’t have access to the detailed logs or backend systems needed to troubleshoot this effectively due to privacy and security constraints. For that reason, the most efficient solution would be to contact Microsoft’s support team directly.    

For the standard procedure outlined above, Office 365 Global Administrators may need to contact the Office 365 support team by submitting a service request.   

Therefore, if you're an end-user, please kindly reach out to your IT Admin for support.

If you are an IT Admin with Office 365 Global Admin role, here’s what you should do next:  

Submit a Service Request: 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

I hope this issue can be thoroughly investigated and resolved soon so that you can return to a smooth and uninterrupted workflow. 

Thank you for your kindness and understanding!

Kindly let me know when there are updates or if you need further assistance. Any updates you’re able to share would be really helpful. I appreciate your time and look forward to hearing how things are going!
